I think the magnetic clip attaches the pencil 2 to the iPad. It uses inductive charging since there is no lightning port on the new iPads and the pencil 2.

Communcationwise, it uses bluetooth to connect to the ipad. The tip is conductive like your finger. I’m not sure exactly, how it figures out location but there must be a sensing grid beneath the display of the iPad something the iPhone doesn’t have.
