This study guide covers magnetism and current-carrying wires, focusing on the magnetic field produced by a wire (strength and direction using the Right-Hand Rule #1) and the force on a wire in a magnetic field (magnitude and direction using the Right-Hand Rule #2). It includes key formulas, vector addition of magnetic fields, and common exam pitfalls. High-priority topics include calculating field strength and force, applying right-hand rules, and combining these concepts to solve problems.
