#### Question

A solenoid of length 1.5 m and 4 cm in diameter possesses 10 turns per metre. A current of 5 A is flowing through it. The magnetic induction at a point inside the solenoid along the axis is ............................. .

(μ_{0} = 4π × 10^{-7 }Wb/Am)

- π × 10
^{-5}T - 2π × 10
^{-5}T - 3π × 10
^{-5}T - 4π × 10
^{-5}T

#### Solution

2π × 10^{-5} T
