Vedclass · Answer

(C) The magnetic field strength $(B)$ inside a long solenoid is given by the formula $B = \mu_0 n I$,where $\mu_0$ is the permeability of free space,$n$ is the number of turns per unit length,and $I$ is the current flowing through the solenoid.If a core material is used,the field becomes $B = \mu n I$,where $\mu$ is the permeability of the core material.From this formula,it is clear that the magnetic field depends on the current $(I)$,the number of turns per unit length $(n)$,and the nature of the core material $(\mu)$.The magnetic field strength of an ideal long solenoid does not depend on the cross-sectional area of the coil.
