A circular coil of radius `1*5 cm carries a current of 1*5A`. If the coil has 25 turns , find the magnetic field at the centre.

Explanation

To find the magnetic field at the center of a circular coil, we can use the formula for the magnetic field due to a circular coil:

\[ B = \frac{\mu_0 \cdot n \cdot I}{2 \cdot R} \]

Where:
- \(B\) is the magnetic field at the center of the coil,
