Magnetic Fields of Current-Carrying Wires and the Biot-Savart Law
Study Guide Overview
This study guide covers magnetic fields and forces in AP Physics C: E&M. It focuses on the Biot-Savart Law, calculating magnetic fields of current-carrying wires (especially straight wires and circular loops), and determining the magnetic force on wires in external magnetic fields. The guide includes key formulas, right-hand rule applications, common mistakes, exam tips, and practice questions with solutions.
