Question

Consider a solenoid of length L, N windings, and radius b (L is much longer than b). A current I is flowing through the wire. If the radius of the solenoid were doubled (becoming 2b), and all other quantities remained the same, the magnetic field inside the solenoid would

    Answer:

    The magnetic field remains the same.

    Explanation:

    If a solenoid has length L, N windings, and radius b, then the magnetic field inside the solenoid is given by :

    B=\mu_o NI

    \mu_o is magnetic permeability

    If the radius of the solenoid were doubled and all other quantities remained the same, the magnetic field inside the solenoid would remains the same as it is independent of the radius of the solenoid.
