# Magnetic field around spinning sphere

1. Homework Statement

So there's a sphere, and it has a positive charge on it. The sphere is spinning, and the angular velocity vector is pointing up through the top. What does the magnetic field look like inside & outside the sphere?

2. Homework Equations

none

3. The Attempt at a Solution

This is what I think it looks like outside of the sphere, but I'm not sure what it would look like inside...

Which equation do you use to figure out the magnetic B-field due to moving charges (current)? That is certainly a Relevant Equation for this problem.

F=qvBsin(theta) ?

I dont see how this is relevant though, since I am not asked to calculate anything, simply draw in the magnetic field lines

can anyone tell me if im thinking about this right? i dont need any equations I just need to be able to draw the magnetic field
