I test a Neodymium Super Magnet magnet to see if lives up to its promise. I paid full price for this magnet, this is an honest evaluation.
This is a followup to my Dangerous Super Magnet Unboxing and Safety Testing video here:
• Dangerous 3" Super Mag...
Here is the magnet used in the video: amzn.to/3bh1UqP
you might be able to find one stronger and cheaper on Amazon.

4:36 "260 and still holding" lmfao i love you, that made me laugh, thanks for posting! just the tests i needed to see
Doctor Kankle, thanks for the comment. It was intended to not be too serious. Glad you understood.
@@MakeItorBreakItNow LoL> I was waiting for that "260 n still holding" point. Laughing in tears (of happiness)
@@armgod1 glad my video brought a little chuckle into your day.
Layers of steel are not comparable to solid steel. That's one of the principles behind the electrical transformer.
Dave, agreed. It's just what I could find rather easily. Thanks for the feedback.
not really, Dave - transformers use layers of steel because they work JUST AS GOOD as whole chunk of steel for the magnetic force. They use layers for different reason: they want to prevent eddy currents induced by the alternating currents. In his tests he does not use electric current, so the solid block of steel or sheets - no big difference if you neglect small air gaps between them.
Inserting a grippy material or using a rubber coated magnet does increase the friction between the surfaces, which can prevent it from sliding down. However, since the magnet is now farther away from the steel surface, it has a much lower pull force.
It is not completely static Load, there is a dynamic load added due to the swinging and the great effect of the air gap between the metal sheets which resist the loop of magnetic flux .
ehab nour, all valid points. Thanks for the feedback.
Sorta like how car audio subs are rated? They say a 10” sub was rated at 1,000 wattts BUT, ignoring the fine details that were much closer to it’s actually power when used as marketed. So a 1,000watt Peak power output subwoofer 🔊 was probably a 500 watt RMS or continuous power output
At any rate, good job showing us what this “neato-beem-him-up” super magnet 🧲 can do!
OMG that is some dangerous testing !
not really, we weren't that far off the ground and took precautions. Next time though I would do things differently and make the test rig even safer.
It’s also swinging so the effected it
James, thanks for the feedback. I've thought about the swinging, but looked at the video quite a bit and the swinging was over when the magnet popped. I've been thinking about doubling up on the steel again to see if that would make a difference.
Good review
Thanks Will for the comment, much appreciated.
When they tested the magnet I bet they did it with all weights and it was stationary so there was no swings ng on it. It is still a super magnet. Awsome testing
george, thanks for the feedback.
I'm glad you had them pads there lol
BillySparkman. thanks for the comment. Yeah the pads helped.
None scientific but still very enjoyable
3:03 alright, this information and the fact you say sideways it doesn't work as well, made me decide to go with the heavy one, just for some more drag sideways, right
Can you do more this video was excellent
Thanks. I try to improve with each video I make.
Swinging weight isn’t the same as static weight as it includes forces of inertia…I’d say when they tested it they attached the weight first and pulled straight up (probably slowly). Still a pretty good test I’d say.
russjordan, agree. Swinging does impact the result. If I were to do this test again, I would change quite a few things. Thanks for the feedback.
Great video! Which magnet on Amazon would you recommend to buy?
ys6425, Here is the magnet similar to the one used in the video: amzn.to/3wDrtL2 you might be able to find one stronger and cheaper on Amazon by shopping around starting from this link. in fact, I I'm looking for another magnet and get this one myself. Thanks you're comment.
Ok I was gonna say...good call on the helmet lol
Thanks David, this is one of my earlier videos, we've ramped safety a lot since then.
Swinging will cause more weight as well as you jumping onto it cause an initial weight plus the air gap in between the plates of steel will also give a weaker hold and the carbon ratio of the steel will also give a different result
Ryan Jones, all valid points. When I designed this test I was thinking about magnet fishing and snagging something heavy on the bottom. But if I were to do it over I would certainly incorporate all your thoughts above. Thank you.
Hello please tell me if I can use a 20 kg force magnet to extract the end of a sim card pin ejector stucked in my android phone. Thanks for your help
I had that. Use a needle or thin metal object.
After sticking how you remove it
😳🤣🤣🤣 Lmfaoo.....the best part is when he said 260 and still holding.....and 2 seconds later he crashing on the floor....damn near falling out the garage 🤣🤣🤣🤣🤣
King Romeo, glad you liked it.
It depends on what alloy you are using for your test as well since different alloy mixtures will have an effect on attractive force. I would eliminate the metal alloys and go with 100% Iron. That will give you a much different result for magnetic force.
Guile, all very good points, 100% iron would attract best. The goal here was to do a simple test, and see what happens. A future test I would do from here would be much more detailed.
Good video and I gained information towards some product research I’m acquiring. The kid really should have worn a helmet though. If it did fail with him on it that magnet would have been pulled down onto his head with all its weight and then some! 🤕
Drone operator, thanks for the feedback. In hind sight I would do the video differently now. BTW they were never in danger, there were two of us at the ready to catch them just off camera and keep them safe.
Never in danger?🤔 Let's have a metal magnet with 100+ lbs worth of a force aimed directly above someone's skull. When the magnet can't hold anymore, the force goes straight down.. but we have 2 people close to catch after he gets knocked out, fractured skull, and a concussion. No one's in danger though..
@@curtisrich7372 This. As a mother, I found that part hard to watch.
I am a 300 pound man I want to hang a hammock in my bus which has a metal roof what size magnets would you use so I don't hit the floor ?
Chef Santa, there's 2 things to consider. 1) the strength of the magnet. and 2) as I learned doing this video the amount of backplate you have is just as critical. If your bus doesn't have 1 inch thick steel spars or I-beams you're at risk with any power magnet, because that is how they rate the strength. Since most busses survive rollover they must have a fairly beefy structure... Since you mentioned roof, remember these magnets are designed to be strongest when the loads are perpendicular to the face of the magnet. Any angle and you won't get the rated strength of magnet. If I knew more about the roof structure I might be able to give you a better answer.
Man when he hold the magent close to metal i my hand feels like it was crushed and i almost did get my finger crushed by a neoduim magent it was 1 inch cube and the other magent came and broke skin only but am lucky i didnt lose a finger
Linda, thanks for the feedback. I'm glad you didn't lose your finger these magnets are dangerous.
they tested it on a solid 1/2" steel plate not 5, 1/10" steel plates solid plating would give a stronger pull strength
Dlink Travis, valid point. That is one of several things I would change if and when I update this video and do it again. Thanks for the feedback.
I wanted to buy some magnets for rock hunting and found this... I was looking at a 18 pound pull weight
Anthony, here's some that might work for you,amzn.to/2NPSj2x they're more than 18 lbs but have eyes and are priced right. Here's another good deal: amzn.to/2NYFqmI
in fact I just order some for myself.
@@MakeItorBreakItNow Thoes looked pretty good
Where can I buy one
Roger, here's a link to the magnet similar to the one in this video: amzn.to/3lfs9Co
dang i think i over did it. ordered a 600lb one cus i didnt believe it. i only want it cus i lost something in a back wall of my backyard and i'd use it to fish it out. im kinda intimidated. its guna arrive in a day or two.
It's hard to tell on these magnets. Recommend you be careful were you work with this. I almost lost mine while magnet fishing in a spillway when it started to cling onto a metal conduit. Make sure your line is strong enough to give it a good yank without breaking. Good luck.
@@MakeItorBreakItNow and now i realize i wear steel toed boots all the time.
@@Magician12345 , be careful out there...
This is a followup to my Dangerous Super Magnet Unboxing and Safety Testing video posted here: kzhead.info/sun/pZaDpdCNen95o58/bejne.html Check it out.
I'm definitely getting one for the price damn its cheapest I've seen
danger
the setup was more safe than it looks. But if I were to do it again I'd wear a harness, and clip into the wall. Thanks for your comment.
2:25 - that obviously wasn't safe. Wise move making your kids do it.
Point taken. Thanks for the feedback.
TEST SUBJECT :D
Yup, aren't we all at some point in our lives?
Gonna get a headache !
Control Man, maybe so.
Magnet direct(upside down)pull force is strongest
Trista, excellent point, agree. Of course not all applications on a super magnet are a static load.
your test is invalid though for 2 reasons, one, magnets don't handle impact well and two you and the weight rocking adds weight, still your video holds great value anyways, thank you
Thijs van Gisbergen, thanks for the feedback. There are several things I would change if I was to repeat this test. In a sense I was also trying to simulate the reaction of the magnet while fishing and snagging a heavy object from the bottom. In those cases the magnet rocks and slides similar to how it did in this test setup. Trying to test pulling up a 200-300 lb load from under water would be challenging in other ways, first its wet and second things on the bottom usually get covered with gunk rather quickly and buried over time.
All of the above reasons is why I invented this new magnet fishing rig you can see the test video here: kzhead.info/sun/hNF7kraRjqFqbJs/bejne.html Thanks again for your feedback, always appreciated.
You would have got well over 300, if not cleared 350, if you would have went about it better. When they test these, the force is pulled completely straight, as in not swinging back and forth like you were. As well, its hard telling how much force you were putting on it initially when you were literally jumping on it hard enough to make the weight's clink together. They actually recommend that you remove these magnets from things by doing exactly what you are doing. You are supposed to put force at an angle to be able to remove them. If you would have been able to make sure the force was exerted fully vertically, straight, without movment, and applied steadily and not in a jerking motion, you would have gotten a lot more accurate results.
The Real One, agree with your assessment. If I was to do this over again I would have rigged a more refined setup, and used a solid 1/4 steel plate. I learn every time I do a video and will put your thoughts into practice next time.
Make It or Break It by sandwiching the thin plates together you are not achieving the same effect as if you had a solid 1/2” by say 6” square plate, the small gaps between the plates will have a huge impact, anything from paint, to dust, mud, oil, rust or other magnetic debris will decrease the holdings power of a magnet by a huge factor, sometimes over 70%, that is without taking the angled pull into account which as stated above already, has a major impact on measured pull capacity. A 1/4” plate as you mentioned would not capture the full magnetic potential of your magnet, much of the field of attraction would be escaping out the other side of the plate, I would very much like to see how it performs on a 1/2” solid steel plate with a larger footprint.
Go put it on a steel bridge and see if it comes off. Too many people cry about these magnets cause they don't understand they need lots of steel to meet their full potential.
Fish 4 Fun, thanks for the suggestion, I'll consider it, may make a good video. Something to consider, most of the things that people would be magnet fishing for would probably not be made of one inch steel plate either.
It's also based on how thick of steel even our lifting magnets at work needb1.5 inch to do 2000 lb
bentlikeitsmaker, agreed. I've learned a lot since I made this test. Thanks for sharing.
I think you would of easily done it if you went swinging
Lee Soulsby, thanks for the feedback. Your point is valid. If I redo this test I'd make several changes. ll add your suggestion into the mix.
❤️Anybody noticed Made In India 🇮🇳
I'll have to check the magnet, I didn't notice. Thanks for the comment.
hey
hey Marsh
Your test is highly uncontrolled. From what I saw it's most likely between 300-350lbs. You need solid steal for molecular reasons and a nice gradual centered pull. 1 you were swinging pulling the tention off cent while also adding G's. Second it looks like your using galvanized steel. Not as magnetic then iron steel
Zach Bishop, thanks for your feedback. Your points are valid. If and when I do a test like this again I would do it quite differently.
Ads?👎🏼 🔕 Reports with Repulsive Content😭 Otherwise cool magnet, poor science
J3GJ, thanks for your feedback. Yeah you can't please everyone. And when your teens want to help with videos you got to figure out ways to keep them safe.
1.56 sec ( is that your son???) i hope he still alive!!! ,who put a kid under an unsafe experiment? what if turns out the magnet is not that strong ???whos head is going to land on??? me respect for the experiment !!! what you are using for rat lab is a human!!!!
They should not say it can do that. 250lb magnet! Must be from China😂 I hope a American manufacturer would do better☺
Brute Magnetics is an American company.
