Statement 1: Self inductance of a long solenoid of length L, total number of turns N and radius r is less than $\frac{π μ_{0} N^{2} r^{2}}{L} .$
Statement 2: The magnetic induction in the solenoid in Statement 1 carrying current I is $\frac{μ_{0} N I}{L}$ in the middle of the solenoid but becomes less as we move towards its ends.
