Answer:
Explanation:
I1 = 3 A right
I2 = 6.8 A left
Let the distance is r from both the wires on the same side.
The formula for the magnetic field is given by
[tex]B =\frac{\mu _{0}}{4\pi }\frac{2i}{r}[/tex]
As the direction of current in both the wires is opposite to each other
so the net magnetic field is
B = B2 - B1
[tex]B =\frac{\mu _{0}}{4\pi }\frac{2i_{2}}{r}-\frac{\mu _{0}}{4\pi }\frac{2i_{1}}{r}[/tex]
[tex]B =\frac{\mu _{0}}{4\pi }\frac{2\times 6.8}{r}-\frac{\mu _{0}}{4\pi }\frac{2\times 3}{r}[/tex]
[tex]B =\frac{\mu _{0}}{4\pi }\frac{7.6}{r}[/tex]
