Vedclass · Answer

(B) The magnetic intensity $H$ inside a solenoid is given by the formula $H = nI$,where $n$ is the number of turns per unit length and $I$ is the current flowing through the solenoid.Given:Number of turns per unit length $n = 1000 	ext{ m}^{-1}$Current $I = 2 	ext{ A}$Relative permeability $\mu_r = 400$ (Note: This value is not required to calculate magnetic intensity $H$,as $H$ depends only on the geometry and current).Substituting the values into the formula:$H = 1000 	imes 2$$H = 2000 	ext{ A m}^{-1}$$H = 2 	imes 10^3 	ext{ A m}^{-1}$Therefore,the correct option is $B$.

$A$ solenoid has a core of a material with relative permeability of $400$. The solenoid windings are insulated from the core and carry a current of $2 \text{ A}$. If the number of turns is $1000$ per meter,then the value of magnetic intensity will be . . . . . . .
