Document Summary

The si unit of magnetic flux is the weber (wb) or the tesla-square meter. As a result, the direction of an induced emf is that of the induced current. 30-2 induction and energy transfers: when induction of a current occurs, the energy from changing flux is being transferred to the current, this energy can be transferred into thermal energy. The rate at which thermal energy appears can be calculated through: eddy currents swirl within conducting plates as opposed to conducting loops, wherein the induced currents follow a single path. 30-3 induced electric fields: a changing magnetic field produces an induced electric field, regardless of whether there is a real or physical conductor. The induced emf of such a field is expressed as: as a result, faraday"s law can be applied to, electric potential is only applicable for electric fields that are produced by static charges, not induced electric fields.
