Magnetic Permeability: A measure of how easily a material can become magnetized, indicating the ability to support the formation of a magnetic field within itself. Faraday's Law of Induction: A law stating that the induced electromotive force (EMF) in a coil is proportional to the rate of change of magnetic flux through the coil.

It covers the relationships between electric fields and charge distributions, the roles of electric and magnetic potentials, and the derivation of Laplace’s equation under partial charge knowledge. Quasistatic conditions enable simplifications in analyzing field interactions.

It is the change in magnetic field that creates the current in the following way: a changing magnetic field induces an electric field, which results in the induced voltage. The faster the motion, the greater the voltage, and there is no voltage when the magnet is stationary relative to the coil.
