Pardon my comment, but why on earth would you want to make specialty, rare-earth magnet yourself when there are very wel qualified companies with vast experience at the process? Sounds kin of like wanting information on how to make an integrated circuit i your basement
I am an inveterate Do-It-Yourselfer, but there are limits. You ar
unlikely to save money by trying to make magnets at home. I requires knowledge of and sources for the specific, exotic material and the appropriate mix/alloy for the properties you want, sinterin furnaces, dies and presses, precise temperature control, ability t apply the correct magnetic field while the material is above th Curie temperature, specialty coatings and ability to bake them o (if you use powder coatings) without depolarizing your magnet, etc. etc
"Physics Today" 2003 Buyers' Guide lists a dozen or two magne
manufacturers. Go to
formatting link
select (M)agnets permanent (or the category you want), and you get the list
"magnets, permanent" brings up
Angstrom Sciences Inc.
Dexter Magnetic Technologies Inc. Global Equipment-Magnetics Division Integrated Magnetics MagnaPlan Corp. Magnetic Component Engineering Inc. Magstar Technologies National Imports LLC TeachSpin, Inc.
One or more of them may even have what you need as a standard item i
their catalog, or at least have dies to make what you need.
Good luck
