Question

A solenoid of $ 1.5 \mathrm{~m} $ length and $ 4.0 \mathrm{~cm} $ diameter has $ 10 $ turns per $ \mathrm{cm} $. A current of $ 5 $ A is flowing through it. The magnetic field induction at axis inside the solenoid is, $ 2 \pi \times 10^{-7} $ Gauss, $ 2 \pi \times 10^{-5} $ Gauss, $ 2 \pi \times 10^{-5} \mathrm{~T} $, $ 2 \pi \times 10^{-7} \mathrm{~T} $

MARKS App · Accepted Answer

Magnetic field inside the solenoid and is given by, B = μ 0 n i = 4 π × 10 - 7 10 0 .1 5 = 2 π × 10 - 5 T
