Description

Technical Field

[0001] The utility model relates to the technical field of nondestructive detectors, and particularly relates to a nondestructive detector which is convenient to adjust. Background Art

[0002] The nondestructive detector applies the principle of electromagnetic induction to detect metals. All metals, including iron and non-iron, have high detection sensitivity. When ferromagnetic metals enter the detection area, they will affect the distribution of magnetic force lines in the detection area, and thus affect the magnetic flux within a fixed range. When non-ferromagnetic metals enter the detection area, eddy current effects will be generated, which will also change the magnetic field distribution in the detection area.
