Vedclass · Answer

(A) The magnetic field $(B)$ inside an ideal solenoid is given by the formula:$B = \mu n I$Where:- $\mu$ is the permeability of the medium inside the solenoid.- $n$ is the number of turns per unit length.- $I$ is the current flowing through the solenoid.From the formula, it is clear that the magnetic induction depends on the permeability of the medium, the number of turns per unit length, and the current flowing through it. It does not depend on the radius of the wire.Therefore, the correct quantities are $(a)$, $(c)$, and $(d)$.

The magnetic induction produced inside an ideal solenoid depends on which of the following quantities?
$(a)$ Number of turns per unit length $(n)$.
$(b)$ Radius of the wire.
$(c)$ Current flowing through it $(I)$.
$(d)$ Permeability of the medium $(\mu)$.
