Magnetic Fields and Forces

This AP Physics 2 study guide covers magnetism, focusing on magnetic fields. It explains how moving charges create magnetic fields and cause materials to become magnetic through magnetic domain alignment. The guide visually illustrates magnetic field lines, their direction, and how they represent field strength (B, measured in Teslas). It details the magnetic force on moving charged particles using the formula F = qvBsin(θ) and the Right-Hand Rule. The guide also explains the magnetic force on current-carrying wires, using the Right-Hand Curl Rule to determine field direction and the formula B = (μ₀I)/(2πr) to calculate field strength. Finally, it emphasizes key exam topics, common question types, and provides practice multiple-choice and free-response questions.
