A `0.5` m long solenoid has 500 turns and has a flux density of `2.52 xx 10^(-3) `T at its centre. Find the current in the solenoid.

Explanation

To find the current in the solenoid, we can use the formula for the magnetic field (B) inside a solenoid, which is given by:

\[ B = \mu_0 \cdot n \cdot I \]

Where:
- \( B \) is the magnetic flux density (in Tesla),
