Where are eddy currents produced?

Eddy currents are produced in conductive materials when they are exposed to changing magnetic fields. This phenomenon occurs due to electromagnetic induction, where the varying magnetic field induces loops of electrical current within the conductor. Eddy currents can be generated in various applications, such as in Transformers, electric motors, and induction heating systems. They can also occur in natural phenomena, such as in geological formations subjected to magnetic field variations.
