Massive 600 kg (1300 lbs) Neodymium Magnet [4k]
51 Comments


Hello everyone! In this video, we will show you a massive
neodymium permanent magnet assembly weighing more than half a ton. This magnet made of rare earth elements represent
the strongest class of permanent magnets. In this video, we first will see what happens
when you approach it with ferromagnetic materials (like steel) and then afterwards we will explore
how conductive metals behave in a strong magnetic field. Here is a wrench and a scale for measuring
the pull of magnet which reaches 25 kg while the wrench itself is only 1 kg. On larger ferromagnetic objects attraction
can easily reach hundreds of kilograms. Next up is a hammer! Note that I added 5 cm (2 inches) layer wood
so not to damage the surface and to be able to “easily” remove it. Even with this added distance pull force is
around 40 kg. Afterwards, a flexible iron sheet is placed
to the magnet which illustrates the distance where objects are visibly attracted. The permanent magnet of such size is stronger
than earths magnetic field in a radius of 4 meters around it and can turn screens of
a laptops from 1.5 meters away Ferromagnetic objects from iron are drawn
to magnet form half a meter away as illustrated with iron sheets. We continue experiments with placing a ferrofluid
on the magnet. This reveals the spikes on the surface. These spikes are acting (pointing) like magnetic
field lines so in a sense you can visualize the magnetic the direction and strength of
magnetic field. Sometimes the camera loses focus because of
the strong magnetic field interferes with electronics and sensors. The ferrofluid contains very tiny magnetite
particles, which acts as tiny magnets and when the external field is applied they aligned
in “spiky” structures pointing in the direction of the magnetic field vector. When in close proximity to poles the magnetic
forces dominate over gravity making so the fluid can defy gravity. If I were to let, go the container it would
fly towards the pole of the magnet to the spot with the highest magnetic field intensity. Next up we take 4 kg copper sheet and when
we throw it towards the magnet it rapidly slows down. When the plate is getting closer to the magnet
it moves noticeably slower. All that happens because of the induced current
in the copper sheet. Copper is an excellent electrical conductor
and when it is moved in a magnetic field, the changing flux creates eddy currents according
to the Maxwell’s-Farady’s law of induction. In short, these currents create an opposing
magnetic field and overall damps movement of copper and that is why it is extremely
difficult to move the copper sheet next to a magnet. And this simple demonstration perfectly showcases
the effect opposing forces caused by induction. Normally plate of such size would fall down
in a second, however, since it is placed in a strong magnetic field (which changes in
plate during fall) it takes almost 20 seconds for it to hit the ground. In the end for a bigger effect, we took a
20 kg copper sheet and rolled it in a cylinder and which we dropped on the magnet. The first attempt was with a couple of centimeter
gap. The copper sheet is slowed down up until it
reaches the center of the magnet. At that point, the magnetic flux becomes negative
and current changes direction. In the second attempt, we shrunk the gap to
5 mm. In both cases, it is overwhelmingly slowed
down by induced currents. Thanks for watching and if you enjoyed it

  1. i just have a problem with 3:49to the end.
    i spent the time to find it and wouldn't post it if it wasn't educational
    https://www.youtube.com/watch?v=nV4yA8OYwmE
    i just do not understand why it drops like a rock as soon as the whole copper sheet is around the magnet.

  2. Wow so many questions about this beast how did you construct it? Individual sections magnetized and bolted together?

  3. With this magnet you can't catch UFO from space or satellite πŸ‘πŸ˜‚πŸ˜‰ I think this magnet it's so strong that can't destroy your phone or something electronic with this power !

  4. What website did you use to get each piece of this monster magnet? They look like 6X2 sized each to make that monstrosity! Thanks!

  5. Dude plz make with this copper plate something like a gloves and try to punch this magnettttt, omgg you Willl be crazy 😜

  6. this is kinda fishy, such magnet should definitely attract all this stuff with much, MUCH greater force. unless its very low grade magnet like N30 or the actual magnet is concealed inside the cylinder and further separated by ~5 cm air pocket
    a 50×150 N52 disc magnet can lift up a 1.2 ton of ferromagnetic material like iron

  7. Can you swing this magnet at a dense copper wall and measure the heat created as the copper brings the pendulum swing to a standstill. It may be dramatic. Can you also rotate the magnet near a dense copper wall and measure the temperature change too please. Thanks!

  8. now that is some serious magnet…. don't stay to long near it tough… the iron from ur blood might stick to it. I hope you encase that thing in a 20cm of wood….

  9. Would You like to conduct an experiment for me ? I try to verify this Podkletnov effect

    https://www.researchgate.net/publication/26460495_A_Theory_of_the_Podkletnov_Effect_based_on_General_Relativity_Anti-Gravity_Force_due_to_the_Perturbed_Non-Holonomic_Background_of_Space

    however I believe there is no superconducter needed. I think that two nd magnets in a repulsing configuration could do the job.

    If You are interested I give You the detailed explanation and also the scheme to do the experiment.

    Cheers, Gregor R.

  10. How on earth did you put this together? I watched Brainiac combine two 6"x2" magnets, and that was a major operation.

  11. What is the grade of that huge piece of shit, like low quality N5? Even Chinese eBay sellers with cheap n35 magnets would easily replicate what you're showing in 1/20th the size. So you're full of sopping wet diarrhea shit and know you're lying or you're a hapless, clueless, dimwitted lamebrain who "jus dun kno anything but 2 be a goof hyuck! Hyuck!" and your "gigantic 600kg magnet" is actually a much much smaller one wrapped in a large metal housing as would be expected from a part so large that could have been a piece of an MRI or something like an extremely accurate scientific measuring or testing device.

  12. Could you create a form of artificial gravity by having one magnet pulling down on a reference frame while another magnet pulls from the opposite direction? Kind of how you increased the weight of the wrench by 25? Instead of you pulling on the wrench another magnet pulls on the wrench? Hell in a spacecraft you could have magnets surrounding an entire area and apply specific voltage to the magnets so you could keep a constant 9.8 ms2. So when the craft is moving it uses the acceleration in addition to the magnets to fake gravity. Idk maybe it’s impossible.

  13. Same magnets size repulsion test will be great test.. how strong can they can repel to each other

  14. What if you place the the magnets with n-n and S-S ? What would be the distance between them? How thick is one of those magnet?

  15. Iv always wonders is thare a force between to very large magnets if you pout ur hand in between them when u turn one around
