Abstract

Permanent magnets, especially Nd-Fe-B magnets are very important engineering elements that are widely used in many applications. Detailed design of electrical and electronic equipment using permanent magnets requires precise measurement of magnetic characteristics. We developed a measurement system which can measure the magnetic characteristics of permanent magnets precisely. This paper presents the measured results of magnetic characteristics of various types of permanent magnets and comparison of these characteristics.
