Diamagnetism and Paramagnetism: classical or quantum phenomena?

[Paul Potter]

Are Diamagnetism and Paramagnetism classical or quantum mechanics phenomena?

I am looking for a simple explanations of these phenomena.

Yes.

Can I claim the prize please?

What- you want a better answer?

OK how about

 

 

Diamagnetism is certainly not classical; it lets you violate Earnshaw's theorem which relies on moving electric (or magnetic) fields emiting energy.

I think paramagnetism is quantum too.

An electron "orbiting round a nucleus" shouldn't be stable, nor should a "spinning" charged particle.

 

Feel free to give the cash to charity.
