Electromagnetic device, method and apparatus for selective application to vertebrates
First Claim
1. A multifunction device for selective application to the body of a vertebrate comprising:
- a coil;
a ferromagnetic plunger reciprocally secured within the coil for movement in a substantially axial direction with respect to the coil, the plunger defining a base end and a striking end;
a permanent magnet disposed in close proximity to the base end of the plunger, the permanent magnet being structured to magnetically attract the plunger when the coil is not energized, whereby the plunger is biased away from the coil;
the coil being structured so that, when the coil is energized, a resulting magnetic field biases the plunger towards the coil; and
the coil further being structured to induce a magnetic field within the plunger that is oriented in a direction that will cause the plunger to be repelled from the permanent magnet when the coil is energized.

Abstract
A multifunction device for selective application to the body of a vertebrate is disclosed. The device includes an electromagnetic generator supported by an bobbin like member which has a bore therethrough for reciprocally receiving an elongated magnetizable member. A permanent magnet is disposed near one end of the bore. The magnetic poles of the permanent magnet are arranged to magnetically attract the elongated magnetizable member. When energized, the electromagnetic generator produces a magnetic field magnetically polarizing the elongated magnetizable member establishing a repelling magnetic force with the permanent magnet which is additive to the electromagnetic force caused by the electromagnetic generator moving the elongated magnetizable member away from the permanent magnet.
