Problem
Two long parallel wires A and B are 6cm apart and carry equal currents of 10A in opposite directions.
(i) What is the direction of the magnetic field at the point exactly midway between the wires?
(ii) Will the magnitude of the net magnetic field at this point be zero or non-zero? Give reason.
