I'm designing a circuit, and I'm going to use 1020 steel for an end cap. Can someone tell me, or point me to, a way to determine the dimensions of the cap for it to be slightly less than saturated by the flux from the pole of an n35 magnet?
I use Moskowitz's 'Permanent Magnet Design & Application Handbook' extensively as a reference.
Are there any other good books I should make room for on my bookshelf?
