A conductor of radius a is surrounded by a conducting tube of inner radius b and outer radius c. Both conductors carry unknown currents distributed uniformly over their cross sections At points located in the empty space between both conductors (a < r < b) the magnetic field is B =( 6 × 10^−6)/ r) T ⋅ m pointing in a counter-clockwise direction. Determine the current I1. Image 1 At points located outside both conductors (r > c) the magnetic field is B =( 4 × 10^−6)/ r) T ⋅ m pointing in a counter-clockwise direction. Determine the current I2. Image 2
