Study Guide Overview

This study guide covers magnetic fields created by currents, focusing on the Biot-Savart Law, Ampère's Law, and solenoids. It explains how to calculate magnetic fields from wires using the Biot-Savart Law, including the right-hand rule and the permeability of free space (μ₀). Ampère's Law and solenoids are also mentioned as topics covered.
