Expert Answer:

Dear student,

An alternator converts mechanical energy (from rotation) into electrical energy via electromagnetic induction. This is the core of most of our electrical power plants, and is how all electricity is generated except in electrochemical systems.The coil, split ring, brushes and magnet are exactly the same hardware as the motor , but the coil is being turned, which generates an emf. If you use mechanical energy to rotate the coil (N turns, area A) at uniform angular velocity ω in the magnetic field B, it will produce a sinusoidal emf in the coil.
