Consider a solid sphere of radius r and mass m which has a charge q distributed uniformly over its volume. The sphere is rotated about the diameter with an angular speed ω. Show that magnetic moment μ and the angular momentum l of the sphere is related as,
The Attempt at a Solution
I know that μ=ql/2m is a general result and q/2m is gyromagnetic ratio and is same for every body of given charge distribution, mass and angular speed and is independent of the shape.
But how to derive it for solid sphere ?
Now to find magnetic moment:
How to proceed after this ??
Please help !!
Thanks in advanced... :)
