An infinitely long cylindrical pipe with inner radius R1 = 8.00 cm and outer radius R2 = 12.0 cm lies along the z-axis centered at the origin. If the pipe carries a current of ipipe = 2.00 A k, then: a)

An infinitely long cylindrical pipe with inner radius R1 = 8.00 cm and outer radius R2 = 12.0 cm lies along the z-axis centered at the origin. If the pipe carries a current of ipipe = 2.00 A k, then: a) Using Ampere’s Law, what is the magnetic field at the point P = (x, y, z) = (0.00, 0.75, 0.00) m? b) A long straight wire is placed parallel to the z-axis along the line (x, y, z) = (0.00, 2.00, z) m. What must the current in the wire be so that the magnetic field at point P is equal to O T?
