Claim 10:
11. The keyboard system of claim 1:
wherein the first magnetic element comprises:
a first magnet:
arranged over the first inductor on a first side of a primary axis of the first inductor; and
defining a first polarity facing the first inductor; and

a second magnet:
adjacent the first magnet;
arranged over the first inductor on a second side of a primary axis of the first inductor opposite the first magnet; and
defining the first polarity facing away from the first inductor; and

wherein the controller is configured to drive the oscillating voltage across the first inductor during the first haptic feedback cycle to:
induce alternating magnetic coupling between the first inductor, the first magnetic, and the second magnet; and
oscillate the tactile layer, at the first key location, parallel to the substrate.
