A long cylindrical dielectric rod of radius r and length l (l>>r) carr – InterviewSolution

1.	A long cylindrical dielectric rod of radius r and length l (l>>r) carrying uniform charge of surface charge density sigma on its curved surface is rotating with a constant angular velocity omega. About its own axis. Find magnetic induction at the centre of the rod. Relative magnetic permeability of the material of the rod is u( read as Miu).
