Problem
Two long, parallel conductors A and B separated by 8cm carry currents IA=20A and IB=30A in the same direction.
(a) Show that there exists a point on the line joining the conductors where the net magnetic field is zero.
(b) Calculate the distance of this point from conductor A.
(c) Find the magnitude and direction of the magnetic field at the midpoint of AB.
