The magnetic field 40.0 cm away from a long, straight wire carrying current 2.00 A is 1.00 μT.
(a) At what distance is it 0.100 μT?
(b) 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 it is one-tenth as large?
