Electromagnetic Induction
PHYS 301 · Module 5
This module explores how changing magnetic flux produces electric fields and currents. Students learn Faraday's law, Lenz's law, inductance, magnetic energy storage, and AC circuit behavior.
Lessons in this module
Faraday's law of induction
Faraday's law states that changing magnetic flux induces emf. This lesson explains magnetic flux, induced electric fields, generators, and motional emf.
Lenz's law
Lenz's law gives the direction of induced currents and emfs. This lesson explains opposition to flux change, energy conservation, eddy currents, and magnetic braking.
Inductance and inductors
Inductors resist changes in current by inducing emf. This lesson introduces self-inductance, RL circuits, magnetic energy, and energy density.
AC circuits
Alternating current circuits involve sinusoidal voltages and currents. This lesson introduces reactance, impedance, phase, RMS values, resonance, and power.
