Is diamagnetism only present with varying magnetic fields?

Click For Summary
SUMMARY

Diamagnetism is a phenomenon where materials repel magnetic fields, and it is not limited to varying magnetic fields. The discussion clarifies that while Ampere's law relates to electromotive force, diamagnetism is fundamentally explained by Lenz's law and Faraday's law. When a magnetic field, whether constant or varying, is applied to a current loop, the induced magnetism acts in opposition to the applied field, resulting in a repulsive effect. This understanding is crucial for accurately interpreting the behavior of diamagnetic materials.

Hello. I was wondering if diamagnetic materials only repel varying electric field? By Ampere law only a variable flux can cause an electromotive force, so, and by what I understood diamagnetism is explained exclusively by Ampere law. Am I wrong?

When I said electric field I meant magnetic field.

Sorry about that!

I don't know what you mean by "Ampere law"?
Diamagnetism is caused by Lenz's law. In classical terms, if a magnetic field (constant or varying) is applied to a current loop, the loop tends to rotate in a direction so that its magnetic field acts against the applied magnetic field. This produces magnetism (M) in the direction opposite to the applied magnetic field.
 
I meant Faraday law, sorry.
It was early in the morning
