In a hydrogen atom , an electron of charge e revolves in an orbit of radius r with speed v . Find the magnetic moment associated with the electron .

Text Solution

Verified by Experts

Time period of revolution of the electron , `T=(2pir)/(v)`
equivalent current , `I=(e)/(T)=(ev)/(2pir).`
`therefore` The magnetic of the electron ,
`p_(m)=IA=(ev)/(2pir).pir^(2)=(1)/(2)evr`
