Question

A is situated in the direction from O​

Answer 1

Answer:

A magnetic dipole is situated in the direction of a magnetic field.

Step-by-step explanation:

If the magnet be rotated from an initial orientation θ1=0o to final orientation θo=180o,

The total work done 

W=∫θ1θ0MBsindθ

W=MB[−cosθ]θ1θ0

where B is magnetic field induction and M is magnetic moment.

W=MB(−cos180o+cos0o) 

W=MB(1+1)=2MB
