Current from a Spinning Cylinder (
Current from a Spinning Cylinder
A solid cylinder with radius \(R\) and height \(H\) has its base on the \(x,y\)-plane and is symmetric around the \(z\)-axis. There is a fixed volume charge density on the cylinder \(\rho=\alpha z\). If the cylinder is spinning with period \(T\):
Find the volume current density.
Find the total current.
