Homework Statement
Consider a non conducting ring of radius r and mass m which has a total charge q distributed uniformly on it.The ring is rotated about its axis with an angular speed ω.
a)Find the equivalent electric current in the circuit.
b)Find the magnetic moment μ of the ring.
Homework Equations
The Attempt at a Solution
I know how to solve this problem .But I am finding it difficult to understand whether a rotating charge actually constitutes a current.If we consider any cross section of the ring then it looks like charge passes through it.But the cross section itself is moving .
I found a thread https://www.physicsforums.com/showthread.php?t=187946 somewhat related , especially post#5 by DaleSpam .But haven't been able to understand properly.
I would be grateful if someone could help me understand this.
