Answer» wo infinitely LONG parallel wires a and b carrying current of 10A and 20A respectively in opposite. direction are placed at a separation of 30 CM.To find:Position where the Magnetic field will be ZERO?Calculation:The required position (point P) will have the field intensity EQUAL and opposite to one another :So, point P is 30 cm from 10 Amp WIRE and 30+30 = 60 cm from 20 Amp wire.
