An electron moving around the nucleus with an angular momentum / has a magnetic moment

A

`(e)/(m)l`

B

`(e)/(2m)l`

C

`(2e)/(m)l`

D

`(e)/(2pim)l`

Text Solution

Verified by Experts

The correct Answer is:
B

An electron moving around the nucelus has a magnetic moment `mu_1` given by
`mu l = (e)/(2m) l`
where l is the magnitude of the angular momentum of the circulating electron around the nucleus. The smallest value of `mu_l` is called the Bohr magnetour `mu_B` and its value is `mu_B = 9.27 xx 10^(-24) J T^(-1)`
