A solenoid consists of 250 turns of wire and has a length of 20 cm. Calculate the magnitude of the magnetic field inside the solenoid if it carries a current of 1A.

Explanation

To calculate the magnitude of the magnetic field inside a solenoid, we can use the formula:

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

where:
- \( B \) is the magnetic field inside the solenoid,
