Physics

An electric motor is a device that transfers electrically storedenergy into kinetic energy. A very crude one would consist of aconducting wire shaped as a loop with a steady electric currentpassing through it placed in a uniform magnetic field. Let'simagine that the magnetic field is directed along the positivexx-axis, which we'll set up as going from left to right. Theyy-axis points up and the zz-axis points out. Assume an absence ofany frictional effects.

Which combination of options below are the most accuratecombination of statements? [Enter your answer as a string of theletter options you believe are correct. For instance, if you thinkoptions A, D, and E are correct, then enter \"ADE\"]

A) If the current loop's dipole moment is initially aligned withthe field, then it will flip back until it is anti-aligned, andthen forth.
B) Maximum potential energy in this system occurs when the dipolemoment points in the −i^−i^ direction
C) If the dipole moment initially points along the k^k^ direction,it's left end will feel a force pushing in along the −k^−k^direction.
D) If the dipole moment initially points along the k^k^ direction,it's right end will feel a force pushing out along the k^k^direction.
E) None of the above
