    Answer:

    magnetic field strength increases.

    Explanation:

    No, the solenoid will not attract any magnetic substance if it does not carries a direct electric current.

    The formula for the magnetic field strength of the solenoid is given as:

    B=\mu.n.I

    where:

    \mu= permeability of free space

    n= no. of coil turns in the solenoid

    I= current in the coil

    So, when the current & no. of coil turns in the coil are increased then the magnetic field strength also increases.
