Magnetic field due to currentHard
Question
An infinitely long hollow conducting cylinder with inner radius R/2 and outer radius R carries auniform current density along its length. The magnitude of the magnetic field, 
as a function ofthe radial distance r from the axis is best represented by
as a function ofthe radial distance r from the axis is best represented byOptions
A.
B.
C.

Solution
Inside the cavity, B = 0
Outside the cylinder,
In the shaded region
at r = a, B = 0
at r = b, B =
