Actually, I've been looking around and I think that for my application I'll use a rod magnet wrapped in ferromagnetic material with a mu-metal shield around that. Hopefully that will allow the field loops to pass through the ferro material while limiting the spread of the field. As soon as I...
Possible to modify a magnet to be more "beamlike"
I've been wondering if it is possible to encase a magnet in something readily available that would give it more beam-like characteristics vs. field. Basically, I want to have the magnet encased so that I would get full magnetic pull on an...
