1. A magnetic circuit element used in combination with an adjoining core of a solenoid that has an axis, the magnetic circuit element comprising:
a plate including a soft magnetic material and having a face configured for contact with an axial end face of the core to form a magnetic path in combination with the core to conduct a magnetic flux,
wherein the plate:
forms a disk shape defining an opening around the axis, and
is dimensioned as to extend the face from an inner periphery to an outer periphery of the axial end face of the core; and
one or more tabs forming a unitary body with the plate and projecting at least radially outward.
