Medium$A$ solenoid of $1000$ turns per metre has a core of material with relative permeability $400$. The windings of the solenoid are insulated from the core and a current of $2 \ A$ is passed through the solenoid. Then the value of the magnetic intensity inside the solenoid is
- A$2 \times 10^3 \ Am^{-1}$
- B$1.0 \ Am^{-1}$
- C$8 \times 10^5 \ Am^{-1}$
- D$794 \ Am^{-1}$
