The resolution of the paradox associated with this law invokes Le Chatelier's [lih SHAHT uh lee airz] Principle to Lorentz forces on electrons; that paradox concerns a disk generator spinning against a brush.

Homopolar generators and, in fact, all generators and motors make use of the consequences of this law. The negative sign indicates that it incorporates Lenz's Law, and Joseph Henry discovered it inde- pendently from its namesake. Identify this law of electrodynamics, one of Maxwell's equations, that can be written as the curl of the electric field equals negative the partial derivative of the magnetic B-field with respect to time, or as the induced electromotive force equals negative the change in magnetic flux with respect to time, and explains how a current is produced in a loop of wire turning in a magnetic field.
