A solenoid $0.5$ m in length has $200$ turns and carries a current of $0.5$ A, as shown in the figure. Find the magnetic field strength at the centre of the solenoid $(\mu_0 = 4\pi \cdot 10^{-7} \frac{N}{A^2})$
The image shows a solenoid of length $0.5$ m, with $200$ turns. A current of $0.5$ A is flowing through the solenoid.
