Question

You may recognize the figure below from an earlier homework. It, however, represents a very different physical situation: this is now a very long (infinite for our purposes) conducting wire in the form of a cylindrical shell. The inner radius of the shell a=2.3 mm and outer radius b=4.2 mm. The electric current i=15 A runs along this wire and is distributed uniformly throughout the shell cross-section. This current is the source of the magnetic field, which you will be evaluating, Find the magnitude of the magnetic field B(r) inside the shell body at distance r 1 =3.63 mm from the cylindrical axis: B(r)= G. Find the magnitude of the magnetic field B(12) outside the shell body at distance r2=5.46 mm from the cylindrical axis: Bry)= G.
