Magnetostatics
PHYS 301 · Module 4
This module introduces magnetic fields produced by steady currents and magnetic dipoles. Students study magnetic forces, the Biot-Savart law, Ampère's law, magnetic materials, and dipole behavior.
Lessons in this module
Magnetic force on charges and currents
Magnetic fields exert forces on moving charges and current-carrying wires. This lesson introduces the Lorentz force, circular motion, and force on currents.
Biot-Savart law
The Biot-Savart law calculates magnetic fields from steady currents. This lesson explains current elements, field direction, and applications to wires and loops.
Ampère's law
Ampère's law relates magnetic field circulation around a closed path to enclosed current. This lesson explains line integrals, symmetry, and applications to wires, solenoids, and toroids.
Magnetic materials and dipoles
Magnetic materials respond to applied fields through microscopic dipoles. This lesson introduces magnetic moments, torque, paramagnetism, diamagnetism, ferromagnetism, and hysteresis.
