Magnetic Particle Testing (MT)

COURSE INFORMATION

Magnetic Particle Testing (MT) is a surface and shallow subsurface non-destructive testing (NDT) method that leverages the inherent magnetic properties of materials to uncover surface flaws and significant indications just beneath the surface. The material being tested must possess magnetic qualities, allowing magnetic fields to be either generated within or passed through it. Consequently, MT is primarily applicable to ferromagnetic materials, characterized by having a magnetic permeability significantly greater than 1.

If you have a keen interest in magnetism and are intrigued by the utilization of magnetic fields to identify discontinuities within ferromagnetic materials, Magnetic Particle Testing is the ideal starting point for your NDT career journey.

The techniques employed in MT vary depending on several factors, including the type of current utilised for magnetisation, whether the excitation current is  maintained during the application of magnetic particles, and the nature of the magnetic field generated—whether it is linear or circular. Additionally, the method description should encompass details about the specific type of magnetic particles employed to render the indications visible, further enhancing the precision and effectiveness of the testing process.

Embracing Magnetic Particle Testing as your chosen NDT path will immerse you in the captivating realm of magnetism, offering a unique perspective on how magnetic fields are harnessed to detect flaws and discontinuities in ferromagnetic materials—a skill set highly sought after in various industries where material integrity and safety are paramount.

IF YOU ARE INTERESTED IN MAGNETISM AND WOULD LIKE TO FIND OUT HOW MAGNETIC FIELDS ARE USED TO DETECT DISCONTINUITIES IN FERROMAGNETIC MATERIAL THEN MAGNETIC PARTICLE TESTING IS THE PLACE TO START YOUR CAREER IN NDT.

Inspection techniques depend on the type of current being used to magnetise the material, whether the excitation current is maintained during the application of magnetic particles or not as well as the nature of the magnetic field generated i.e. linear or circular. In addition the technique description should also refer to the type of magnetic particles used to make indications visible.
