How does this work?

I recently bought a Sonicare toothbrush (ATOT's fault, but great toothbrush) and I noticed that when you put it in the charging stand, there are no metal contacts anywhere. Just plastic. How does this work? I think I saw this somewhere before but I never figured it out...

 

Magnetic induction.

You know how putting magnets near wire induces an electric flow??? Same sort of deal. It uses magnetic fields that generate and collapse to charge the battery I believe. Just an edumacated guess.

How'd they get that in there?!

Ahh, induction. My guess was some type of magnet, looks like I was close.
