Q.

The magnetic potential due to a magnetic dipole at a point on its axis situated at a distance of 20 cm from its center is 1.5×10-5 Tm. The magnetic moment of the dipole is _____. (Given: μ0/4π=10-7 TmA-1)                                 [2024]


Ans.

(6)      The magnetic potential due to a magnetic dipole,

           V=μ04πMr2

           1.5×10-5=10-7×M(20×10-2)2

            M=1.5×10-5×20×20×10-410-7

           M=1.5×4=6
