The magnetic field 40.0 cm away from a long, straight wire carrying a current of 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) The center wire in a coaxial cable carries a current of 2.00 A in one direction, and the sheath around it carries a current of 2.00 A in the opposite direction. What magnetic field does the cable create at points outside the cable?
