A dielectric spheri- cal shell of radius R, having charge `Q` is rotating with angular speed w about its diameter. Calculate the magnetic dipole moment `(M)` of the shell. Write the ratio of M and angular momentum `(L)` of the rotating shell. This ratio is called gyro-magnetic ratio. Mass of shell is m.

Text Solution

Verified by Experts

The correct Answer is:
`M=(QomegaR^(2))/3;M/L=Q/(2m)`
