How Alternators Produce AC Power

Alternators produce alternating current by rotating a conducting loop in a magnetic field. As the loop turns inside the field, the magnetic flux through the coil changes with time. That changing flux induces an emf, or electric voltage, in the circuit.

Electric generators convert mechanical energy into electrical energy. One of the  examples is the simple alternator, which consists of a conducting loop rotating with constant angular velocity, placed inside a constant uniform magnetic field.

As the loop rotates, the magnetic flux through the loop changes. Here, the angle between the area...
