The MAGNASTEER actuator is an integral part of the power steering gear. The MAGNASTEER actuator consists of the following:

When the coil is energized, a magnetic field is formed between the permanent magnet and the pole pieces, which increases the torque on the input shaft to the steering gear. The EBTCM controls the current flow to the coil. As the vehicle speed increases, the EBTCM increases the current flow resulting in an increase in steering effort.

Other power steering system components, while specially modified to use with MAGNASTEER, are similar to non-MAGNASTEER power steering components.
