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.
