If a straight conductor of length 40cm bent in the form of a square and the current 2A is allowed to pass through square, then find the magnetic induction at the centre of the square loop

Explanation

To find the magnetic induction at the center of a square loop formed by bending a straight conductor of length 40 cm with a current of 2 A passing through it, we can follow these steps:

### Step-by-Step Solution:

1. **Determine the Side Length of the Square:**
The total length of the conductor is given as 40 cm. Since the conductor is bent into the shape of a square, the length of each side (A) can be calculated as:
\[
4A = 40 \text{ cm} \implies A = \frac{40 \text{ cm}}{4} = 10 \text{ cm} = 0.1 \text{ m}
