    The vibration is caused by the expansion and contraction of transformer coils at twice the frequency of the alternating current.

    Explanation.

    The phenomenon is called magnetostriction.

    The iron core in a transformer experiences magnetic fields that cause it to expand and contract due to the AC (alternating current).

    The resulting vibration has a fundamental frequency that is twice that of the transformer.

    The vibration produces an audible humming sound.
