A solid cylinder of radius 1.0 cm is carrying a current of 10 A in the direction out of the page. A cylindrical shell of inner radius 2.5 cm and outer radius 3.0 cm carrying a current of 15 A distributed uniformly in to the page is placed coaxially around the solid cylinder. Find the magnitude of magnetic fields at the regions =1.5 cm, r, = 2.7 cm , and at 1; = 4.2 cm.
