When carrying out magnetic inspection cracks are best seen when cracking is in line with current flow and at right angle to the magnetic field.
A nondestructive testing (NDT) technique that serves as a basis for most other nondestructive techniques for ascertaining imperfections and cracks in magnetic metal parts by determining any variations in the magnetic field. The technique determines the presence of variations in the magnetic flux in ferromagnetic materials of a constant cross section caused by defects, variations in hardness, discontinuities, or other irregularities. Also known as magnetic analysis inspection.

Ultrasonic and magnetic inspection of metallic materials is another method that engineers commonly use to locate potential problems with building systems and structures.
Without lubrication, friction increases, causing the magnetic inspection tool to "stick" to the pipe wall.
The project adopted the mobile Electro Magnetic Inspection (EMI) system designed to inspect ferro-magnetic materials based on the well-known principle of the "Electromagnetic Flux Leakage" method.
