Question

an energy associates Thes relate it to work done by the magneto changes. Here we shall avoid the debate and say that U is an energ with the dipole orientation. The place char tial the V Checkpoint 5 The figure shows four orientations, at angle 0, of a magnetic dipole moment quina magnetic field. Rank the orientations according to (a) the magnitude of the torque the dipole and (b) the orientation energy of the dipole, greatest first. А O vº VAB Rotating a magnetic dipole in a magnetic field

Answer 1

can & all Torque = magnitude of the four MB sing. torque dipoles. will be equal for a= 2 = 3=4 e (6) E = - HB – – M B Coso. for i for and dipole 3 & 3 0 = 8z = 0. = – MB cose. for 3 & ② dipole and 6 0 - - a = t + g. coso, - cos (t ) = - Cose cosa 4 = cos(tto a caso. So = {4 = MB caso. . 0 = @ > -3
