For 2-4, consider a very long non-conducting cylinder has an inner cylinder with radius R. and uniform charge density P₁ and a cylindrical shell with inner radius R₁, outer radius R., and uniform charge density p2. The tube moves to the right with a constant velocity parallel to its axis, so that the moving charge in the inner cylinder creates a constant current Ii, and the moving charge in the outer cylinder creates a constant current Iz. 2. Draw and label an Amperian loop and use it to determine the magnitude of the magnetic field at a distance r < R₁ from the center of the central axis of the rod. 0 B(r< R₁)= 3. Draw and label an Amperian loop and use it to determine the magnitude of the magnetic field at a distance R₁ < r< R2 from the center of the central axis of the rod. 0 B(R1 R2 from the center of the central axis of the rod. 0 B(r> R₂) = 5. Explain why, for questions 2-4, the material needs to be non-conducting. (And why example 12.7 in section 12.5 of the OpenStax textbook is problematic, because the "wire" should have been a moving non-conducting material instead.)
