Hi
Couple because of attractive field following up on attractive snapshot of the current coil= M X B in
vectors
Couple = M * B * Sin theta
Theta. = point among M and B.
M = I * N*A = 5*10* 0.02 = 1 units
Couple = 0.3 = 1*B*sin theta
Further, wrt East West:
Couple = 0.4 = 1 *B*Cos theta
Figuring out and including we get
B = 0.5 T
Hope it helps
