Magnetic Fields, Magnetic Forces, and Conductors

When current runs through a wire exposed to a magnetic field a potential is produced across the conductor that is transverse to the current.

When an electrical wire is exposed to a magnet, the current in that wire will experience a force—the result of a magnet field.

A current-carrying loop exposed to a magnetic field experiences a torque, which can be used to power a motor.

Current running through a wire will produce a magnetic field that can be calculated using the Biot-Savart Law.

Parallel wires carrying current produce significant magnetic fields, which in turn produce significant forces on currents.
