1. Faraday’s law of induction is the fundamental law on which electric motors operate. Michael Faraday is credited with discovering induction in 1831, but James Clerk Maxwell described it mathematically and used it as the foundation of his quantitative electromagnetic theory in the 1860s. Inductance is a property of a device that tells how effectively it induces an emf in another device (or on itself). Faraday’s law generally states that in a closed coil (loop) of wire, a change in the magnetic environment of the coil causes a voltage, or emf (electromotive force), to be induced in the coil. The change in magnetic environment can be caused by changing the magnetic field strength, moving the magnet toward or away from the coil, moving the coil into or out of the magnetic field, or rotating the coil in the field. The induced emf equals the negative rate of change of the magnetic flux, times the number of turns in the coil: Where: E = emf (V) N = number of turns in the coil Φ = magnetic f...

Symbols in bold represent vector quantities, and symbols in italics represent scalarquantities, unless otherwise indicated. The equations introduce the electric field, E, a vector field, and the magnetic field, B, a pseudovector field, where each generally have time-dependence. The sources of these fields are electric charges and electric currents, which can be expressed as local densities namely charge density ρ and current density J. A separate equation, the Lorentz forcelaw, describes how the electric and magnetic field act on charged particles and currents. A version of this equation was included in Maxwell's original equations but, by convention, is no longer. In the electric and magnetic field formulation there are four equations.
