Final answer:
The magnetic field of the magnets exerts a mechanical force on the electric charges in the wire loop, causing torque and rotation, resulting in the conversion of electrical energy to mechanical work.
Explanation:
The electric current flows in the loop of wire that turns between an electric generator's two permanent magnets because:
- The magnetic field of the magnets exerts a mechanical force on the electric charges within the moving loop of wire.
- When a current is passed through the loops, the magnetic field exerts torque on the loops, which causes rotation due to the Lorentz force on the moving charges in the conductor.
- This conversion of electrical energy to mechanical work is how electric generators produce an AC voltage that drives an AC current through the loops.
