Rare earth permanent magnets have the widest range of magnetic properties and are used in anextensive variety of applications. Sintered NdFeB magnets have the highest maximum energy product (BH)maxbut are limited to applications with relatively low temperatures. Sintered Sm2Co17-type magnets have the best thermal stability with high magnetic performance at temperatures up to550oC. Bonded magnets offer some design flexibility at the expense of magnetic properties. Inview of these complexities, it is very important to understand the critical factors when designing themagnetic circuit. The magnetic properties, maximum operating temperature, reversible temperaturecoefficient of Br of permanent magnets will be discussed from a design standpoint. Design exampleson travelling wave tubes and magnetic couplers will be discussed based on finite element analysis(FEA).
