Torque on a current-carring loop
Description
When current is passed through the loops, the magnetic field exerts torque on the loops, which rotates a shaft. Electrical energy is converted to mechanical work in the process. Motors are the most common application of magnetic force on current-carrying wires. Motors have loops of wire in a magnetic field.
