1. A controllable differential, comprising:
- a rotatable casing,differential gearing disposed within said rotatable casing, said differential gearing linking said casing with an output element disposed in said rotatable casing;
a clutch disposed within said rotatable casing, said clutch adapted to transfer torque between said rotatable casing and said output element; and
an electromagnet arranged to generate a generally toroidal magnetic flux path encircling said electromagnet and magnetically forcing said clutch into engagement with said rotatable casing;
said casing including an endcap, said endcap comprising a nonmagnetic portion adjacent said electromagnet, and a magnetic portion, said magnetic and nonmagnetic portions secured to each other, said flux path surrounding said nonmagnetic casing portion.
