# Question no. 7

Dear Student

The magnetic field due to loop will be zero.The net magnetic field will be due to the wires coming from infinity.

The magnetic field due to wire is given by

$=\frac{{\mu}_{0}I}{2R}\phantom{\rule{0ex}{0ex}}Where{\mu}_{0}=4\mathrm{\pi}\times {10}^{-7}\mathrm{T}-\mathrm{m}/\mathrm{A}\phantom{\rule{0ex}{0ex}}$

Now putting the values

$B=\frac{4\mathrm{\pi}\times {10}^{-7}\times 5}{2\times 5\times {10}^{-2}}\phantom{\rule{0ex}{0ex}}B=2\mathrm{\pi}\times {10}^{-5}\mathrm{T}\phantom{\rule{0ex}{0ex}}$

Now for directions, According to right hand thumb rule, magnetic field is coming out of plane.

So option D is the correct answer.
