Given a cylinder of length L, radius a and conductivity sigma, how does one find the induced currenty density (J) as a function of p when a magnetic field B is applied?(adsbygoogle = window.adsbygoogle || []).push({});

Where p is the distance from the axis of the cylinder and B is applied along the axis of the cylinder, B = Bosin(wt).

(Neglecting any additional fields due to the induced current)

Hence, how does one calculate the power dissipated in the cylinder?

Thanks

Denis
