A solenoid of length $\displaystyle 0.5$ m has a radius of $\displaystyle 1$ cm and is made up of ' m ' number of turns. It carries a current of $\displaystyle 5$ A. If the magnitude of the magnetic field inside the solenoid is $\displaystyle 6.28 \times 10^{-3} \mathrm{~T}$ then the value of m is $\displaystyle \_\_\_\_$.
