A magnetic dipole is acted upon by two magnetic fields which are inclined to each other at an angle of 750. One of the fields has a magnitude of 15 mT. The dipole attains stable equilibrium at an angle of 300 with this field. The magnitude of the other field (in mT ) is close to :
11
36
1
1060
As we learnt in
Torque -
- wherein
M - magnetic moment
For stable equilibrium, net torque acting on dipole must be zero
or,
