The factor that is MOST essential for the induction of the electric current is:
**D the movement of the magnet relative to the coil.**
Electromagnetic induction occurs when there is a change in the magnetic field around a conductor, such as the movement of a magnet near a coil, which induces an electric current.
**D the movement of the magnet relative to the coil.**
Electromagnetic induction occurs when there is a change in the magnetic field around a conductor, such as the movement of a magnet near a coil, which induces an electric current.
