Question

wo equal electric currents are flowing through two infinite long wires kept along x and y axis as shown in the figure. The equation of line on which we can expect the resultant magnetic field to be zero is



Options:


y = x

y = – x

y = 2x

y = –2x

Answer 1

answer:

y=x

explanation;

Magnetic field due to long current carrying wire.

At any points on line y = x the point will be equidistant from both wires and magnetic fields are in opposite direction.
