The magnetic field B due to a current- carrying circular loop of radius 12cm at its center is `0.50 xx (10^-4) T`. Find the magnetic field due to this loop at a point on the axis at a distance of 5.0 cm from the centre.

Explanation

To find the magnetic field at a point on the axis of a current-carrying circular loop, we can follow these steps:

### Step 1: Understand the Given Information
We know:
- The radius of the circular loop, \( R = 12 \, \text{cm} = 0.12 \, \text{m} \)
- The magnetic field at the center of the loop, \( B = 0.5 \times 10^{-4} \, \text{T} \)
- The distance from the center of the loop to the point on the axis, \( x = 5 \, \text{cm} = 0.05 \, \text{m} \)
