A long solenoid is formed by winding 70 turns cm^-1. If 2.0 A current flows, then the magnetic field produced inside the solenoid is ____ (μ_o=4 π ×…
A long solenoid is formed by winding $\displaystyle 70$ turns $\displaystyle \mathrm{cm}^{-1}$. If $\displaystyle 2.0$ A current flows, then the magnetic field produced inside the solenoid is $\displaystyle \_\_\_\_$ $\displaystyle \left(\mu_o=4 \pi \times 10^{-7} \mathrm{TmA}^{-1}\right)$
Official answer
From NTA’s final answer key for this paper.
(1)
$\displaystyle 176 \times 10^{-4} \mathrm{~T}$
