The electromagnetic actuator is particularly interesting when modeling the magnetic circuit. Usually, the physical model is represented in terms of reluctances or permeances of the magnetic core. This is due to the regular analogy, which makes the well-known correspondence magnetic flux-current and magnetomotive force-voltage.

In dynamic mre, electromagnetic units (actuators) are widely used to generate shear waves in tissue. These actuators exploit the interaction between the static magnetic field b(0) and an annular coil supplied with alternating currents. Therefore, coil movements are restricted to selected orientations to b(0).
The actuator model was then solved assuming that the permanent magnet was in physical contact with the top end of the actuation channel where one of the electromagnetic coils is located. This coil activation action should permit the magnet to be actuated away from the upper end of the actuation channel as a result of the repulsive force.
Electromagnetic actuators are the most widely used of any design at the macro-scale, with small-scale versions also having beendeveloped[4,5].

Electromagnetic actuators convert electrical and mechanical energy into one another. The energy conversion takes place in the so-called air gap which separates the stationary member (stator or fixed contact) and moving member (rotor or moving contact) of the actuator. These actuators produce force and torque by means of magnetic field.
