Defect detection device enabling easy removal of magnetic impurities
A defect detection device enables easy removal of magnetic impurities. The defect detection device has a structure capable of effectively removing magnetic impurities adhered to a magnetic flux leakage detection device for nondestructive inspection of a small-diameter heat transfer tube or a partially saturated eddy current detection system. With the defect detection device, it is possible to minimize adhesion of magnetic impurities that deteriorate the performance of a leakage magnetic flux detection device for nondestructive inspection of a small-diameter tube of ferromagnetic metal material or a partially saturated eddy current detection system. Further, there is an advantage in that it is possible to remove the adhered magnetic impurities from the defect detection device easily.
