An clectron moving in a circular orbit of radius r makes rotations per second. The magnetic moment of the orbital electron is

A

zero

B

`pir^(2)ve`

C

`pir^(2)v^(2)e`

D

`(pir^(2)ve)/(2pi)`

Text Solution

Verified by Experts

The correct Answer is:
B
Current due to orbital motion of electron`I=ev`.Magnetic dipole moment
`M=AI=(pir^(2))(ev)=pir^(2)ve`
