One form of this quantity is represented as the cross product of lambda times magnetization and the derivative of magnetization in the Landau- Lifshitz-Gilbert equation. For an electric dipole, this quantity with a "spin- transfer" variety is equal to the cross product of the dipole moment and the electric field, while for a rigid body, this quantity can be maximized by increasing the distance from the pivot point or increasing the tangential component of force. With units of newton-meters, it is the time derivative of angular momentum. For 10 points, name this quantity, the rotational analogue of force.
