1. A trigger assembly, comprising:
a first magnet;
a plurality of asymmetric poles proximate to the first magnet, each asymmetric pole including a coil and a core configured to generate a force on the first magnet when energy is applied to the coil; and
a trigger rotationally coupled for experiencing torque when the first magnet receives the force from one or more of the asymmetric poles.
