A square loop of side l carries a current i. it is placed as shown in figure. Find the magnetic moment of the loop.

Explanation

To find the magnetic moment of a square loop of side \( l \) carrying a current \( i \), we can follow these steps:

### Step 1: Understand the Magnetic Moment Formula
The magnetic moment \( \vec{m} \) of a current-carrying loop is given by the formula:
\[ \vec{m} = i \cdot \vec{A} \]
where \( \vec{A} \) is the area vector of the loop.
