Question

An electron in an atom is revolving round the
nucleus in a circular orbit of radius 5.3 x 10"
m, with a speed of 2 10 ms. Find the
resultant orbital magnetic moment and
angular momentum of electron (charge
on electrone = 1.6 X 10 C, mass of
electron m - 9.1 x 10 kg.)​

Answer 1

Answer:

The formula of magnetic moment is M=NIA

where N=no. of turns=1

I=Current,

A=Area

M=NIA
