Medium$A$ solenoid has a core of a material with relative permeability $400$. The windings of the solenoid are insulated from the core and carry a current of $4 \,A$. If the number of turns is $500$ per metre,then the magnetizing field is
- A$2 \pi \times 10^3 \,Am^{-1}$
- B$1 \times 10^3 \,Am^{-1}$
- C$4 \times 10^3 \,Am^{-1}$
- DNone of the above
