Abstract
Magnetic control of a ball on a pinball playfield is provided by an electromagnet located on the playfield and a mechanism manually operable by a player for energizing the electromagnet. The energizing mechanism includes a first switch external on the playfield operable by player and a second switch on the playfield which is activated by a ball hitting a target thereon. The first and second switch are connected in series with the electromagnet to control the latter. A timing mechanism is provided to limit the energization of the electromagnet to a predetermined time period.
