Question

Here assume the cat is cylindrical in shape, with radius 0.1m, and that all the charge on that cylindrical outer surface of the cat. Vluc : 0.1 m A) If you spin this cat as in the diagram at 10 rotations per second, what is the amplitude of the cat's magnetic dipole moment? (hint: How fast is the charge moving, in m/s?) lo rotations 10 rotations per second Select one: o 2x 10-7 Am o 5x 10-5 A m2 o 5x 10-2 A m2 o 0.2 Am2 B) Imagine we now apply an external magnetic field pointed to the left. In what orientation will the cat want to 'settle' to minimize its potential energy? (This is also the orientation the magnetic torque will push the cat 'towards!) O o Select one: tail up, head down tail out of the screen, head into the screen O head on the left, tail on the right
