Magnetism & Electromagnetism
Physics
Explore magnetic fields, forces on charges and currents, Faraday's law of induction, solenoids, and electromagnetic waves. Interactive tools let you visualize field lines, compute forces, and see how electricity and magnetism are two aspects of the same phenomenon.
Learning Objectives
- Understand magnetic fields and their sources
- Apply the Lorentz force law to charges moving in magnetic fields
- Calculate forces on current-carrying conductors
- Use Ampère's law to find fields in solenoids and toroids
- Apply Faraday's law and Lenz's law to electromagnetic induction
- Understand the connection between changing fields and electromagnetic waves
