Question

A solenoid of 1000 turns per mettes has a core with relative permeability 500. Insulated windings of the solenoid carry an electric current of 5 A . The magnetic flux density produced by the solenoid is: (permeability of free space $=4 \pi \times 10^{-7} \mathrm{~h} / \mathrm{m}$ )

Select the correct option:

$\pi \mathrm{T}$

$2 \times 10^{-3} \pi T$

$\frac{\pi}{5} T$

$10^{-4} \pi \mathrm{~T}$
