表示素子。 A permanent magnet is provided on the rotating shaft that drives the reversible display body, and one or two opposing permanent magnets are provided.
In a case where two electromagnetic yokes having the above-mentioned protrusions are arranged oppositely with a permanent magnet in between, the display can be made by making the heights of the respective protrusions on the two yokes different. 1. A magnetic reversal display element characterized in that the magnitude of the magnetic acting force of an electromagnet is different between a display state and a non-display state of a body.
