A solenoid of $1000$ turns per metre 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 $= 4 π \times 10^{- 7} H m^{- 1}$ )

Options:

Answer:

Solution:

$B = μ n I = μ_{0} μ_{r} n I$

$B = 4 π \times 10^{- 7} \times 500 \times 1000 \times 5$

$B = π$ Tesla
