What Is a Magnetic Particle Test Used For?

Magnetic particle inspection (mpi) is a non-destructive testing method that can detect surface and subsurface flaws in ferromagnetic materials. Magnetic particle inspection is often carried out to help determine an item’s fitness for use or conformity.

What Is a Magnetic Particle Test Used For?

A magnetic particle test is used to detect surface and subsurface defects in ferromagnetic materials. The test is performed by applying a magnetic field to the surface of the material and then sprinkling magnetic particles on the surface.

The particles will be attracted to the areas of the surface where the magnetic field is distorted, indicating the presence of a defect.

Magnetic particle testing is a nondestructive testing method that can be used on both ferrous and nonferrous materials. It is often used to detect cracks, laps, seams, and other surface and subsurface defects.

The test is performed by applying a magnetic field to the surface of the material. A coil of wire is used to create the magnetic field, and the coil is connected to an electrical power source.

The current flowing through the coil creates a magnetic field. The material to be tested is placed in the magnetic field, and magnetic particles are sprinkled on the surface.

The particles are attracted to areas of the surface where the magnetic field is distorted. These areas indicate the presence of a defect.

Magnetic particle testing is a relatively simple and inexpensive testing method. It does not require special training or equipment, and it can be performed quickly. Magnetic particle
