Monolith Magnets | Twice the Power?

[@michalchik]

I love how using just household objects this guy systematically and carefully measures and manipulates these dangerously strong magnets.

[@Lordeylord]

There... Isn't really any manipulation going on here... He places the magnets in different positions and tests... He does not however in any instance, manipulate, the magnets.

[@Lordeylord]

@@HoursFreeAOLsp you trying to define "manipulate" with the one definition that makes it sound like you are right here is kinda childish, not gonna lie. There are multiple definitions that I know for a fact that you saw when you just googled that and you chose not to copy/paste the secondary description because it proves you wrong. Just as you chose to leave out the fact that he isn't actually manipulating any tools (dials of any sort seeing as how to "manipulate" the tool you would have to be "fine tuning" it.) This guy in no instance does any fine tuning with or any other form of manipulation with these magnets. If he was manipulating them, he would have been changing the variables of the experiments that he was doing, for example: superconducting the magnets or something along those lines to MANIPULATE, and or FINE TUNE the magnets to get a SPECIFIC OUTCOME. He never does anything to the magnets that would alter their physical properties in some sense (like what happens when you manipulate the knob of your car stereo for instance, the knob rotates, and the digits chance, as such you are manipulating the dials) if he did, variables pertaining to the magnets specifically would have been being changed. How could have added a base and produced a static charge to see if the magnets became stronger, then he would have been manipulating them. You copy/pasting a specific definition that you CHOSE, doesn't make you right just because it "sounds" like it when you say it in your head. When you complete the first definition that YOU copy/pasted, it clearly defined the type of manipulation that it is referring to. I'm sure you noticed that though and just choice to manipulate the given situation to try and give yourself a leg up, full proper definition seen below for all you savvy dogs. verb 1. handle or control (a tool, mechanism, etc.), typically in a skillful manner. "he manipulated the dials of the set" Similar: operate handle work control use employ utilize 2. control or influence (a person or situation) cleverly, unfairly, or unscrupulously. "the masses were deceived and manipulated by a tiny group" Similar: exploit control influence use/turn to one's advantage maneuver engineer steer direct guide work orchestrate choreograph

[@Chag69420]

@@Lordeylord so you’re saying that there is a definition where the use in this context is correct?

[@Lordeylord]

@@Chag69420 I'm saying that the definition for manipulations clearly defined what has to be going on for something to be manipulated. There are NEVER any changing variables PERTAINING TO THE MAGNETS. IF THERE WERE VARIABLES BEING CHANGED PERTAINING TO THE MAGNETS, THEN YES THERE WOULD BE MANIPULATION OCCURING. BUT THERE ARE NO VARIABLES PERTAINING TO THE MAGNETS THEMSELVES BEING CHANGED. There is 0 manipulation going on to the magnets here :| end of story.

I love how you were able to determine from the datasheets what the magnets were originally intended for; how version 3 seemed to support that hypothesis, and how you managed to make it very interesting without having any official confirmation or official source footage. I also love the use of the iconography to illustrate the subject and the dangers involved. Very well done with minimal means; consistency is a powerful tool

[@ArsonalTech]

This was fantastic!!!! More magnets please! I'm definitely showing my little brother. And definitely telling him to show his science teacher your videos. So wonderfully done. I'm showing this to as many people as I know. It's spectacular!!!

[@haipingcao2212_.]

_WARNING!_

[@nonavailable1755]

hey, just wanted to point out a problem with the experiment at 5:00: The problem with a single measure experiment - the measuring tape is conducting the magnetic field, and the results would be farther than it would have been without it. Also the problem escalates when the experiment is repeated - if the distances to the measuring tape were modified, even the relative results would be falsified, since we don't know the extent of the magnetic field amplification.

[@TCPUDPATM]

[@D3CD95]

In every of your videos you show us the attraction, could you show us the repulsion? :o

[@brainiac75]

Maybe, but it's a safety issue. Attraction is fully controllable and predictable. Repulsion is not - the magnets really want to turn around unless in a sturdy rig.

[@willyou2199]

I would say repulsion can be easier to set up, put them on a transparent vertical tube so they're only to move up and down, place weights on the top repelling magnet and measure heights. I feel like this can be more qualitative, as the only things in this are gravity and the magnetic repulsion.

[@PleasestopcallingmeDoctorImath]

[@whatevernamegoeshere3644]

The magnet might have slid worse on the alu tape because of Eddy currents

[@anim8dideas849]

[Whatever name goes here] not on something that thin its almost negligible

[@brainiac75]

Could be even if it is quite a thin material. But I also tried sliding the magnet with my hand while applying pressure to the magnet and oddly enough the hard wood seemed more slippery. I wonder if the aluminium tape is thinly coated...

[@whatevernamegoeshere3644]

+Golden Thoughts I have seen 0.5mm sheets falling like a feather between two relatively small magnets. With a magnet of that size, combined with friction, that could work just fine

[@willyou2199]

Actually, the eddy currents would work against (Lenz law) the magnet sliding, meaning whenever the magnet got closer together, the eddy currents would seek to push them further apart, albeit very weakly. This would help reduce friction as they aren't biting on the wood so forcefully.

[@whatevernamegoeshere3644]

The moving direction of the magnet is what gets resisted and the vertical component is not really there I think since the magnet is only moving in parallel with the tape

[@XANApwns]

I don't know if I've mentioned it before, but I love the new intro where the highlighted hazard symbols kind a give a brief overview of the video. Great video as always!

[@rompevuevitos222]

So magnets loose "attraction" when heated?

[@David-pp9jw]

Yes, based on a measurement scale called _Curie Temperature._

[@willyou2199]

Edited to fill in more details and make a more wholesome explaination. A large magnet is is made up of smaller magnets, domains as they're called, these domains are orderly structured single crystal of material that makes up the magnet, but they are still microscopic. Thousands to millions of these domains make up a typical magnet The domains each generate a small magnetic field, It is the aligment of all these domains, forced to line up all in 1 direction, that makes a magnetic strong. Room temperature heat or random vibrations can cause these domains to rotate out of alignment. However, the strong field generated by all the nearby domains keeps individual domains from flipping. This is why magnets retain their strong magnetism at room temperature. When heated, large swaths of domains start to vibrate due to high temperature. Because every domain is now vibrating rapidly, the field generated by the domains (that used to be strong) is now weaker, by virtue of the unstable domain alignment, giving opportunity for individual domains to start flipping. If the temperature is high enough, this causes a cascade effect and the magnet is rapidly demagnetized. This phenomena is much more complicated, 1 complication is that although you lose magnetic strength with heating, it degrades the magnetic strength at a relatively slow rate. At the curie point all magnetism is lost suddenly and abruptly. This points to something deeper happening right at the curie temp (phase change). But for the mean time, you can think of it this way.

[@Eneicia2011]

I always wondered! Thanks!

[@rompevuevitos222]

I have a 3" (76mm) diameter X 2" (51mm) height cylindrical N45 magnet but it is so powerful that I have been unwilling to experiment much with it. Instead I enclosed it inside a solid 4" X 5" block of wood, effectively keeping all objects at least one inch (25mm) away from its surface. In this form it is fairly safe to handle in all sorts of ways and has proved very popular with all my friends and their children. A couple thousand 7mm ball bearings makes it a fascinating toy!

[@markharder3676]

Noahlizard, there's a cute experiment in which you drop a cylindrical magnet through a a copper tube slightly wider than the magnet. It's eerie. If you drop the magnet out in the open - no tube - as a control experiment, then for a second after the magnet enters the tube you wonder what happened to your magnet. Again, Lenz's law (see Damien W's post below.) explains the effect. The magnet starts moving, and moving, it induces a current in the copper conductor which creates its own magnetic field in the direction opposite that of the magnet, which of course slows the magnet. Brainiac could perhaps create a column of square metal circles a little wider than his magnet and try dropping it through. I predict that the magnet will fall in the spaces between the circles, then come to a near stop as it approaches each turn, then fall again. That would make a pretty demonstration of the law.

[@noahlizard7]

Mark Harder, if that could actually be designed and used as a way to combine magnets it would be amazing!

One of the main reasons you get much lower relative strength due to distance is because of the inverse square law. Force on the paperclip should be a linear relationship with the strength of the magnet, but the force on the saw blade and compass will vary with the square of the distance.

[@bardfinn]

Placing the two magnets together alters the magnetic flux, pushing the size of the field outwards in the direction of the poles. Also, you have to consider that the strength of the field at 104 cm being equivalent to the strength of the first field at 101 cm is due to the large quantity of flux that fills the volume of space difference, not just the linear distance difference. Field strengths drop between cube root to square root of distance from source.

Yep, the difference between 104 and 133 cm in the compass is larger than it sounds :)

Aluminium tape induces the Lenz effect, that's why it slides slower, not actually due to friction. It's the same principle behind the Hendo Hoverboard (except copper is used as it is better for it.

Very interesting. However, the magnet was manufactured for energizing a coil around a LARGE MASS ferrous object (not a paper clip. I also assume separation may be in order of a couple hundred microns. (I have no clue why the magnet is flat.????) - Does the same effect hold for a stator and rotor? - How does the proximity vary the forces? - Are eddy currents happening in the magnet? (IE would thin sleeves of magnets separated by dielectrics change the magnetic fields?) Just dumb questions...

[@kaaare]

When you slide a magnet over the aluminium foil you will induce a magnetic field in the foil with the opposite orientation of the movement, which will in turn courses the part of the magnet on the foil to slow down. Same thing would happen if you drop the magnet through a copper tube, the magnet would fall slower, with big magnets they can fall surprisingly slowly.
