Abstract
As one kind of magnetic detecting methods excited by weak magnetic field, the metal magnetic memory testing method was susceptible to be influenced by magnetic interference, thus it was low in sensitivity and reliability, and was difficult to be applied in the practical engineering. An improving magnetic memory detection sensitivity and reliability method was put forward by strengthening the magnetic excitation field. Through analyzing principles of the method, it is concluded that the method can effectively suppress the interference field and improve the detection sensitivity.
