A uniform wire is bent into one turn circular loop and same wire is again bent in two circular loop. For the same current passed in both the cases compare the magnetic field induction at their centres.

Explanation

To solve the problem of comparing the magnetic field induction at the centers of two circular loops formed from the same length of wire, we will follow these steps:

### Step 1: Determine the Length of the Wire
Let the length of the wire be \( L \).

### Step 2: Case 1 - Single Turn Circular Loop
1. When the wire is bent into a single circular loop, the circumference of the loop is equal to the length of the wire:
\[
