Magnetic Fields and Forces (AP Physics C: E&M) — Math expr, Wire current (extended)
AdvancedMagnetic fields arise from moving charges and currents. At the AP Physics C level, the Biot-Savart law and Ampere s law are used to calculate B fields for wires, loops, solenoids, and toroids.
The Lorentz force on charged particles and current-carrying conductors, magnetic flux, and the force between parallel wires are central topics.
