Two long straight parallel wires are oriented north-south. Both wires carry constant current due North and are 20cm apart. The current in one cable is 30A and in the other 40A . a) Determine the magnitude of the total magnetic field induced by the two cables midway between them. b) determine the position between the cables where the total magnetic field induced by the cables is zero. Give your result as the distance from the 30A cable.

Expert Solution
