Abstract
Residual magnetic locks, brakes, rotation inhibitors, clutches, actuators, and latches. The residual magnetic devices can include a core housing and an armature. The residual magnetic devices can include a coil that receives a magnetization current to create an irreversible residual magnetic force between the core housing and the armature.

A method of braking a first element with respect to a second element, the method comprising:
- providing an armature positioned circumferentially with a core housing;
- forming a substantially closed magnetic path between the armature and the core housing in order to create an irreversible residual magnetic force;
- and
- substantially preventing the first element from moving with respect to the second element due to the irreversible residual magnetic force.
A brake for use in preventing a first element from moving with respect to a second element, the brake comprising:
- a core housing coupled to one of the first element and the second element;
- an armature positioned circumferentially with the core housing, the armature coupled to one of the first element and the second element;
- and
- a coil positioned in the core housing, the coil receiving a magnetization current to create a substantially closed magnetic path between the armature and the core housing in order to create an irreversible residual magnetic force and to prevent the first element from moving.
A brake for use in preventing a first element from moving with respect to a second element, the brake comprising:
- electromagnetic assembly means for forming a substantially closed magnetic path, the electromagnetic assembly means coupled to the first element and the second element and including an armature positioned circumferentially with a core housing;
- and
- controller means for providing a magnetization current to the electromagnetic assembly means to create an irreversible residual magnetic force in order to prevent the first element from moving with respect to the second element.
