Barium Oxide Bar Magnet

I like the HDR because it has an electromagnet. OK one of the things I use with an HDR is a Barium Oxide Bar Magnet. It is a mystery as to how this bar magnet can help boost an electromagnet, but my HDR seems to work better.

Folks, more experiments are on their way to understand the inner workings of my unit. Hopefully, these may explain the mystery.
