Rotating Loop and AC Generation

Rotating Loop and the Origin of AC Generation

The loop rotates around an axis perpendicular to the magnetic field. Because the angle between the area vector and B changes in time, the magnetic flux changes, and Faraday's law produces a sinusoidal EMF. Drag on the 3D scene to rotate the camera.
