    Answer:

    We can increase the strength by increasing current in the wire or increasing the number of turns of the coil around an iron core .

    Explanation:

    The magnetic strength due to current carrying conductor carrying current I and having N number of turns is given by

          B = \mu _{0}\times N\times I

    \mu_{O} is vacuum permeability .and its value is equal to 4\pi\times10^{-7} \frac{H}{m}

    .so from the above equation we can see that magnetic strength is directly proportional to the current through wire and no. of turns .
