Magnetism & Induction

Map magnetic fields, discover that electric currents make magnetism, see why moving charges curve in magnetic fields, and uncover Faraday's great discovery: changing magnetism makes electricity. That's the principle behind every generator and transformer. Then steer particles in spectrometers and cyclotrons, and explore why some materials make good magnets.
