A magnetic dipole is placed in the position of stable equilibrium in a uniform magnetic field of induction B. If it is rotated through an angle 180?, then the work done is. (a) MB (b) 2 MB.

Magnetic Dipole Moment

Dear student,

In first case when it is MB then angle 2 is 0 nd angle 1 is 90 in second case angle 2 is 180 nd angle 1 is 0
  • 2
No no put angle 2 180 in first case
  • 2
b) 2MB
 
  • 0
MB(cos0 - cos180) = 2MB
  • 0
