Consider the following classical configuration:
Let's change a few things, lets assume that:
- There is no applied current on the wire & it's stationary.
- The external magnetic field was from a electromagnet that varies over time.
The wire is a thin piece of conductor surface, and the varying magnetic field is perpendicular to it's surface, wouldn't there be eddy currents on the surfaces to react to the change in magnetic field?
As per Eddy current's description:
Eddy currents are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field. - [2]
Eddy currents don't depend on the size of an area, but on the continuity of conductivity of that area?
