1.	Find the orbital dipole moment in a field of dipoles of radius 20cm and angular velocity of 2m/s(in 10^-22 order)(a) 64(b) 76(c) 54(d) 78The question was asked by my college professor while I was bunking the class.This intriguing question originated from Magnetic Dipole in section Magnetic Forces and Materials of Electromagnetic Theory
Answer» Correct ANSWER is (a) 64 To explain: The orbital dipole moment is given by M = 0.5 X eVangx R^2, where e = 1.6 x 10^-19 is the CHARGE of the electron, Vang = 2 and r = 0.2. On substituting, we get M = 0.5 x 1.6 x 10^-19x 2 x 0.2^2= 64 x 10^-22 units.
