How can a magnetic field be used to generate an electric current?


A.

Electric current flows when a stationary magnet causes the magnetic field to change.


B.

Electrons in a wire flow when a stationary magnet causes the electrical field to change.


C.

When a magnet moves near a wire, the domains in the magnet line up and flow through the wire as electric current.


D.

When a magnet moves near a wire, its changing field causes the electrons in the wire to flow as electric current.
