Questions
A magnet of magnetic moment 20 C.G.S. units is freely suspended in a uniform magnetic field of intensity 0.3 C.G.S. units. The amount of work done in deflecting it by an angle of in C.G.S. units is
detailed solution
Correct option is C
Work done, W=MBH(1- cos θ)= 20 x 0.3(1 -cos30o) = 61-32=3(2-3)Similar Questions
