The magnetic field 40.0 cm away from a long, straight write carrying current 2.00 A is 1.00 µT. (a) At what distance is it 0.100 µT? (b) What if? At one instant, the two conductors in a long household extension cord carry equal 2.00-A currents in opposite directions. The two wires are 3.00 mm apart. Find the magnetic field 40.0 cm away from the middle of the straight cord, in the plane of the two wires. (c) At what distance is it one-tenth as large? (d) The center wire in a coaxial cable carries current 2.00 A in one direction, and the sheath around it carries current 2.00 A I in the opposite direction. What magnetic field does the cable create at points outside the cable?
