This study guide covers magnetism and moving charges, focusing on the magnetic fields of moving charges, forces on moving charges in magnetic fields, and the Hall effect. Key concepts include calculating magnetic field strength and direction, the right-hand rule, the cross-product of velocity and field, the Lorentz force, and the relationship between Hall voltage, magnetic field strength, and current density.
