Magnetic Particle Testing (MT) is one of the most widely used Nondestructive Tests. It is a quick and effective test for the detection of discontinuities at or very close to the surface of the object being examined.

As with PT, MT is usually performed in addition to a volumetric NDT. It is limited to those materials that can be effectively magnetized. Fine ferromagnetic particles are applied to the surface of the magnetized parts and align themselves in areas of magnetic flux leakage – indicating the presence of discontinuities. In this course, the students will learn the principles of magnetism as it relates to the detection of flaws in ferromagnetic materials. There are a number of techniques that make MT suitable for a wide range parts with various shapes and sizes. MT can be performed with portable equipment or stationary systems.

This course will be useful for those pursuing a certification in NDT as well as for supervisors, auditors, and others interested in acquiring a comprehensive understanding of this unique test method.’s Magnetic Particle training is a completely video based online course taught by Marty Anderson that covers:
– Basic principles of Magnetism
– Magnetic particle testing theory
– How to perform examinations with both portable and stationary equipment
– Techniques used to perform MT
– Procedures used to perform MT
– Requirements of MT
– How to interpret and evaluate test results

This course meets the recommendations for training as described in SNT-TC-1A.

NOTE: There is RECOMMENDED READING assigned at the beginning of the course. The completion of these assignments in addition to self-study is strongly encouraged and will add to the overall training benefit and time to be credited. It will also better prepare the student for the practical lab/’hands-on” session. It is recommended that the student a log of the self-study time. It is also recommended that the applicable Level III be involved and confirm that the reading and self-study assignments have been completed. This should become a part of the student’s training records which may be used in conjunction with subsequent certifications.


Meets all ASNT ANSI SNT-TC-1A recommendations per CP-105. Students can typically retain 25% to 60% more of the information as compared to traditional classroom training.

Participants can access the course 24/7 from any computer running Google Chrome browser with an internet connection.
