Solution: Click For PDF Version We are considering a hollow cylindrical conductor of radii
Because of the cylindrical symmetry the magnetic field inside the conductor will be circular and will depend on the distance from the axis of the cylinder. We consider an Amperian loop of radius r as shown in the diagram. We now apply the Ampere’s law and write We will now test this formula for different special cases. (a) For
It is the magnetic field outside a wire of radius a carrying current
(b) For
There is zero magnetic field at the surface
(c) For
