I use a latching type relay for a faulted circuit indicator. When a high fault current is sensed the pulse magnetizes a core that pulls a latch down and turns an orange flag to indicate the fault. When power is restored the magnet is pulsed in a different direction to demagnetize the core. The core that is currently in use is a vacozet 258 magnet with a coercivity of about 26 Oe, but I am no longer able to get this magnet. Would anyone happen to know of a magnet at a reasonable cost with a coercivity similar to this.
