Problem
Two long, parallel conductors P and Q are separated by 6cm in vacuum. Conductor P carries a current of 10A and conductor Q carries a current of 15A in the opposite direction. A uniform magnetic field of magnitude 5μT is superposed perpendicular to the plane of the conductors and directed into the page.
(i) Along the straight line joining the two conductors, locate the point(s) where the resultant magnetic field is zero.
(ii) State clearly on which side of the conductor carrying the larger current the null point lies and calculate its distance from that conductor.
