Magnet modification and repair

I had to modify pallet magnet assemblies for non-organ projects. I removed valve stoppers and riveted extension levers to the swing arm to use them as actuators. The blue object is the electromagnet made from blue tape wrapped around the copper coil. That copper wire is about half the thickness of a human hair and is wound around a small white plastic spool, about 1/4" in diameter.

Many of these magnets initially didn’t work because the thin copper wire was broken. If the break happens at the inner end of the coil, there’s no way to fish the wire out to reconnect it, so the only solution is to completely unwind the coil and rewrap it with new wire.
