Electric Toothbrush

can someone tell me how to chage the work of electric toothbrush? its plastic on plastic, where does the charge come from?

inductors. There is a metal coil inside the toothbrush, and one in the charger. The charger passing a current along the wire creates a magnetic field. The field is Stong enough for him to "connect" to the coil inside the toothbrush. Very slowly, it loads.
