Abstract
The magnetic resistance of a magnetic path that passes through a coil () is increased by magnetically dividing a stator core into a plurality of divided cores () in such a manner that the magnetic flux of a permanent magnet () flows through the magnetic path when a projection () of a plunger () magnetically connects the divided cores (), hence the magnetic resistance of the magnetic path that passes through the coil () rapidly changes due to a positional relationship between a gap between the divided cores () and the plunger (), and the magnetic flux that flows through the magnetic path rapidly changes, and moreover a large back electromotive force is produced.
