Figure shows a long straight wire carrying current , and a square conducting wire loop of side i, at a distance 'a' from current wire. Both the current wire and loop arc in the plane of paper. Find the flux of magnetic field of current wire, passing through the loop.

Explanation

To find the magnetic flux of the magnetic field produced by a long straight wire carrying current through a square conducting loop, we can follow these steps:

### Step 1: Understand the Magnetic Field due to a Long Straight Wire
The magnetic field \( B \) at a distance \( x \) from a long straight wire carrying current \( I \) is given by the formula:
\[ B = \frac{\mu_0 I}{2 \pi x} \]
where \( \mu_0 \) is the permeability of free space.
