Let's continue unraveling the secrets of the trackpad, starting with the coils—we were hoping to find some evidence of linear oscillators in the taptic engine, but it looks like it's just a series of electromagnets.

The magnets rapidly push and pull against a metal rail mounted beneath the trackpad, to create a tiny "buzz" of feedback with each click (and a second buzz for a "force click").
