An electron moving in a circular orbit...

An electron moving in a circular orbit of radius `r` makes `n` rotation per second. The magnetic field produced at the centre has magnitude

A

Zero

B

`(mu_(0) n^(2) e)/ ( r)`

C

`(mu_(0) "ne")/(2r)`

D

`(mu_(0) "ne")/(2pi r)`

Text Solution

Verified by Experts

The correct Answer is:
C
`B = (mu_(0) I)/(2r) = (mu_(0) (ef))/(2r) = (mu_(0) "ne")/(2r)`
