Answer:

The demagnetization of ferromagnetic parts in industry is becoming more and more a necessary process. The subsequent processing of demagnetized parts offers decisive advantages in many areas and it improves the quality of the final products (goto application areas).

Current Type Advantages

Direct Current (DC) -from DC generators and storage batteries greater depth of penetration detects defects wholly below the surface field is uniform over part's cross-section

Half Wave Direct Current (HWDC) single phase-from rectified AC sources detects subsurface defects improved particle mobility
