Abstract
Abstract An electromagnetic coil apparatus has an electromagnetic coil for generaing an electromagnetic flux. The electromagnetic coil includes a coil wire wound on a coil bobbin with an end of the wire extending outwardly from the electromagnetic coil. An elastic terminal cap is connected to the coil bobbin with the wire end arranged between the terminal cap and the coil bobbin to eliminate stress from the wire end.
