The magnetic field existing in a region is given by `vecB =B_0(1+(x)/(l))vec k.` A square loop of edge l and carrying a current I, is placed with its edges parallel to the x-y axes. Find the magnitude of the net magnetic force experienced by the loop.

Explanation

To find the magnitude of the net magnetic force experienced by a square loop carrying a current in a magnetic field, we can follow these steps:

### Step 1: Understand the Magnetic Field and Loop Configuration
The magnetic field is given by:
\[ \vec{B} = B_0 \left(1 + \frac{x}{l}\right) \hat{k} \]
This indicates that the magnetic field is in the z-direction and varies with the x-coordinate.
