Lecture

Magnetic Fields and Forces

Description

This lecture covers the Lorentz force on electric charges moving in magnetic fields, the origin of magnetic fields by moving charges, and the magnetic field produced by currents. It also discusses the magnetic field due to a straight wire, the force between parallel wires, Ampère's Law, and the magnetic field of solenoids and toroids. Additionally, it explores ferromagnetism, the magnetic properties of materials, and how ferromagnetic materials enhance magnetic fields. The lecture concludes with a problem-solving example involving magnetic fields and currents.
