The coils are wound around an iron core. They are magnetically connected but not electrically connected. A primary voltage drives an alternating current through the primary coil. The primary coil ...

This is alternating current (a.c.). The output of an alternator ... on the vertical axis and time on the horizontal axis. A - The coil is at 0°. The coil is moving parallel to the direction ...

In other words, an alternating current is produced. If you hold the magnet absolutely still inside the coil, no current is generated at all. Another way of producing the current would be for the ...
