Feature:Sintered rare earth magnets are manufactured by a powder metallurgical process which involves the sintering of powder compacts under vacuum. Magnets may be produced in large blocks for subsequent processing, or as tailor made components made die pressing. Coatings may be applied depending on the exp...

Feature:Ferrite magnets are also good for doing repulsion and attraction experiments since some of the rare earth magnets may be too strong and steel bar magnets will demagnetize. The plain ferrites shown below are all magnetized through their thickness.

Feature:Bonded NdFeB magnets are manufactured by binding rapid-quenching NdFeB powder. The powder is mixed with resin to form a magnet by compression molding with epoxy or infection molding with nylon. The latter technique is particular effective in large volume production, though the magnetic value of prod...

Feature:Chemical analysis for sintering NdFeB magnets material based on intermetallic compounds RE2Fe14B,main composition is NdFeB magnet is (RE), (Fe) (B),thereinto thulium (Nd), in order to obtain different performance can instead by thulium of (Dy),(Pr) etc. also other metal can instead Fe,for example (C...
