Magnetic field around spinning sphere

AI Thread Summary
The discussion centers on determining the magnetic field generated by a positively charged, spinning sphere with its angular velocity vector directed upwards. The user expresses uncertainty about visualizing the magnetic field lines both inside and outside the sphere. They seek clarification on the relevance of equations related to moving charges, particularly questioning the necessity of calculations for simply drawing the magnetic field. The focus is on conceptual understanding rather than mathematical computation. Overall, the thread emphasizes the need for guidance in visualizing magnetic fields in this specific scenario.

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?

Homework Equations



none

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 don't 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 I am thinking about this right? i don't need any equations I just need to be able to draw the magnetic field

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
