A long pair of insulated wires serves to conduct 20.5 A of dc current to and from an instrument. A). If the wires are of negligible diameter but are 2.8 mm apart, what is the magnetic field 10.0 cm from their midpoint, in their plane (Figure 1)? B). Compare to the magnetic field of the Earth of 5.0×10^−5T
