Vedclass · Answer

(A) For an ideal solenoid of infinite length,the magnetic field inside is given by $B = \mu_0 n i$,where $n$ is the number of turns per unit length and $i$ is the current.This expression shows that the magnetic field $B$ depends only on the number of turns per unit length and the current,making it independent of the total length $l$ and the cross-sectional area $A$ of the solenoid.Inside an ideal solenoid,the magnetic field is uniform and parallel to the axis.Therefore,both the Assertion and the Reason are correct,and the Reason correctly explains why the field is independent of the solenoid's dimensions (as the uniform field is a property of the ideal solenoid model).Thus,the correct option is $A$.

Assertion: The magnetic field produced by a current-carrying solenoid is independent of its length and cross-sectional area.
Reason: The magnetic field inside the solenoid is uniform.
