Abstract
A low energy magnet actuator allows magnetic fields to be turned on and off using a small amount of energy. The magnetic actuator according to the invention generally includes a base suitable for the support of a plurality of magnets. An actuatable shield is positioned in relation to the plurality of magnets so that it effectively blocks the magnetic field when it is positioned over at least one of the magnets. The magnetic fields of the plurality of magnets interact in a manner that allows low energy actuation of the shield.
