Magnetism involves moving charges.

This is a very revolutionary topic. It is how Motors and AC current, and thus modern Electricity works.

Here’s a summary by, myself, Steven Gong.

Current (moving charges) automatically generates magnetic field, given by Biot Savart Law or Biot Savart Law or Ampere’s Law.

However, can we do the opposite, generating current from magnetic field? I.e., do magnetic fields automatically generate current? How do they relate?

Well, not quite. Only the change in magnetic field (magnetic flux) creates current.
