Q1

A long solenoid is formed by winding 70 turns \(\mathrm{cm}^{-1}\). If \(2.0 \mathrm{~A}\) current flows, then the magnetic field produced inside the solenoid is \(\left(\mu_0=4 \pi \times 10^{-7} \mathrm{TmA}^{-1}\right)\)

a

\(88 \times 10^{-4} \mathrm{~T}\)

b

\(176 \times 10^{-4} \mathrm{~T}\)

c

\(352 \times 10^{-4} \mathrm{~T}\)

d

\(1232 \times 10^{-4} \mathrm{~T}\)
