				   Consider a hollow cylinder. The inner radius r1=1 and the

outer radius r2=2. Assume the cylinder has a current of I ampere flowing through it.
a. Derive an expression for the magnetic field in the hollow part of the cylinder i.e.
for rb. Derive an expression for the magnetic field between r1 and r2, i.e. for r1c. Derive an expression for the magnetic field outside the cylinder, i.e. for r>r2.
