The magnetic moment of an electron orbiting in a circular orbit of radius r with a speed v is equal to:
Text Solution
Verified by ExpertsThe correct answer is:
A
Magnetic moment μ μ = niA
Where n = number of turns of the current loop
I = current; Since the orbiting electron behaves as a current loop of current i, we can write
A = area of the loop = π π r 2 
= 
.
