A magnet of total magnetic moment `10^(-2)hati " A-m"^(2)` is placed in a time varying magnetic field, `Bhati(cosomegat)` where B = 1 Tesla and `omega` = 0.125 rad/s. The work done for reversing the direction of the magnetic moment at t = 1 second, is :

A

`0.01J`

B

`0.007 J`

C

`0.028 J`

D

`0.014 J`

Text Solution

Verified by Experts

At t=1 is `B=1 cos (0.125xx(360^(@))/(2pi))~~1:. omega =2mB=0.02J`
