摘要：

This paper presents results of experiments in an open magnetic circuit by designing a magnetic flux measurement setup which consists of self-adhesive coils without frames: the leakage magnetic flux which exists between the coil and the permanent magnet is the main source of errors. It's shown that the coil should have the greater width, the thinner thickness, smaller diameter and the coils should be close to the permanent magnet to minimize the errors. Meanwhile, it's shown that the velocity of sample passing through the coil doesn't affect the results.
