Chapter 9 Magnetic Forces, Materials and Inductance

Chapter 9 Magnetic Forces, Materials and Inductance. The magnetic field B is defined from the Lorentz Force Law, and specifically from the magnetic force on a moving charge: F = qv x B 1. The force is perpendicular to both the velocity v of the charge q and the magnetic field B.
