This study guide covers magnetic fields and forces, including forces on moving charges and current-carrying wires. It explains key formulas like F = q(v × B) and F = ILBsinθ, emphasizing the right-hand rule for determining force direction. The guide also covers magnetic fields generated by currents, including the field around a long wire using the formula B = (μ₀I)/(2πr). Finally, it explores the Biot-Savart Law and Ampère's Law, focusing on the latter's application for calculating fields in symmetrical situations.
