Abstract: A new kind of nondestructive test sensor and measuring system were developed based on the electromagnetic coupling numerical analysis technique, skin effect, and component magnetic flux. Through inspection by means of scanning on the surface of the object, defects and their sizes were found out by measuring the component of magnetic flux density. Some application examples in engineering were also introduced.

- Nondestructive testing /
- Component of magnetic flux /
- Skin effect
