Loops of wire in a motor rotate because a?

Loops of wire in a motor rotate because they are placed in a magnetic field and carry an electric current, which generates a magnetic force due to the interaction between the magnetic field and the current. This force acts on the wire loops, creating torque that causes them to spin. As the loops rotate, the direction of the current is often switched to maintain continuous motion, allowing the motor to operate effectively. This principle is based on electromagnetic induction and is fundamental to the operation of electric motors.
