It is not the luminiferous ether, but in the Trouton Noble experiment, a zero measure for this quantity caused a null result for changes in the orientation of a parallel-plate capacitor. In a type of motion, the absence of this phenomenon causes the right-hand-sides of the Euler angles to become zero, and it is given by the magnetic moment cross the b-field for a current loop. When the angle between the spinning and vertical axis remains constant during rotation, the precessing motion is said to be induced to this phenomenon. This vector quantity is equal to the rate of change of angular momentum. For 10 points, identify this quantity which describes the force required to push open a door at various distances from the hinges.
