Question

Two parallel wires carry 1-A currents in unknown directions. The distance between the wires is 10-cm. What is the magnitude of the magnetic field B in Teslas at a point P located 6-cm away from the axis of one of the wires and 8-cm away from the axis of the other wire?
Unot=4pi×10^-7

Answer 1

Hint: your teacher made a 3-4-5 triangle for you, which means the two B fields are at 90 degrees to each other, so when they add or subtract, magnitude does not change, just direction.

Find B from each, and then add them as 90 degree vectors..

c= sqrt(a^2+b^2)

Answer 2

Can't get it, Didn't studied this topic, Would you please work the solution.

Answer 3

But radius is not given
