Is this feasible /sci/?

Also, magnets general. Feel free to post similar quandries

>> No.1634676

Yes. Thats how they store antimatter

>> No.1634691

Its an unstable equilibrium. If you get the coin in the perfect spots the magnetic and gravitational forces will cancel, but move the coin a nanometre and the forces become unbalanced, and this unbalanced force pushes the coin further away from the perfect spot.

Yes, but it has to be perfectly balanced.

>>1634676
Because we've created enough antimatter to actually store.

We can already levitate living organisms with magnets, why would we stop at cans?

How is antimatter contained?

It is very difficult to contain antimatter, because any contact between a particle and its anti-particle leads to their immediate annihilation.

For electrically charged antimatter particles we know how to contain them by using ‘electromagnetic traps’. These traps make it possible to contain up to about 1012 (anti-) particles of the same charge. However, like charges repel each other. So it is not possible to store a much larger quantity of e.g. antiprotons because the repulsive forces between them would become too strong for the electromagnetic fields to hold them away from the walls.

That's because water is slightly anti-magnetic (perimagnetic or some shit). So a strong enough magnetic field below it levitates it. Magnetic materials (ferromagnetic) cannot be levitated with a static magnetic field, because there is no stable configuration. You can only do it with an electromagnet that you switch on and off while monitoring the thing you're trying to levitate.
