Abstract:
This paper analyzes the biased magnetic field produced by permanent magnets. The magnetic force produced by permanent magnets is compared with that produced by electromagnets. With the structure of bearings biased with permanent magnets analyzed, this thesis puts forward the theory as to the practical use of bearings biased with permanent magnets.
