Introduction to Magnetism and Induced Currents

Magnetic fields permeate space and are strongest near a permanent magnet or electromagnet IThe SI unit for B is the tesla 1 T = 1 Vs/m 2 The tesla is a fairly large unit of magnetic field so we often list magnetic field strengths in terms of Gauss 1 G = 10 4 T The magnetic field of the earth is about one half gauss in strength.
