摘要:

A method of building up a magnetic circuit from strips of sheet material has been found which permits testing for magnetic properties either by d.c. or a.c. methods just as in the case of the ring sample but without the inconvenience of the ring sample in that a permanently wound test frame similar to that of the Epstein test may be used. In testing this magnetic circuit an approximate method may be used where simplicity of testing and consistency of results are required rather than absolute accuracy. For tests where absolute accuracy is more important than simplicity of testing, a comparative test has been developed. Satisfactory results may be obtained by these methods on materials with permeabilities as high as 100,000.
