Sign with flippable pixels, pixels flipped by current flowing in flat spiral coil

In a sign made up of flippable pixels, each pixel is flippable to display a bright or dark side. The pixels are flipped by a magnetised core which extends through a bore 30 in the board 35. Conductors 41a, 41b form a flat spiral around the cores, so that current flowing in the conductors magnetises...
