Abstract
In Chap. 1 Sect. 1.10 we discussed the history of Faraday’s discovery that a time rate of change in the magnetic field induction causes an electric field. In his experiments Faraday measured electrical current. The electrostatic field is conservative (\(\mathrm{curl}\vec{E} =\vec{ 0}\)) and unable to move charges through a circular wire. The electrodynamic field that that is induced by a sudden change in the magnetic field induction is, therefore, of a different character than that resulting from charge densities.
