A coducting circular loop of area `1mm^2` is placed coplanarly with a long, straight wire at a distance of 20 cm from if. The straight wire carries an electric current which changes from 10A to zero is 0.1 s. Find the average emf induced in the loop in 0.1 s.

Explanation

To find the average emf induced in a conducting circular loop due to a changing current in a nearby straight wire, we will follow these steps:

### Step 1: Understand the Problem
We have a conducting circular loop with an area of \(1 \, \text{mm}^2\) placed at a distance of \(20 \, \text{cm}\) from a straight wire carrying a current that changes from \(10 \, \text{A}\) to \(0 \, \text{A}\) in \(0.1 \, \text{s}\). We need to calculate the average emf induced in the loop during this time.

### Step 2: Convert Units
Convert the area of the loop from \( \text{mm}^2 \) to \( \text{m}^2 \):
\[
