Document Type and Number:
WIPO Patent Application WO/2019/047396
Kind Code:
A1
Abstract:
A dynamic magnet detection system (10) and detection method, and an electromagnetic array control method, the dynamic magnet detection system (10) comprising: a magnetic field applying device (100) for applying a magnetic field to a ferromagnetic object (900) to be detected; a dynamic magnetic stimulation device (200) for generating a transient exciting magnetic field; and a magnetic field detection device (300) for detecting an induction magnetic signal around the object (900) to be detected. The present invention can detect the defect of a small dimension and has a high precision, and keeps a stable detection performance while moving at a high speed.
