This ndt method is used for the detection of surface an near to surface discontinuities in ferromagnetic materials,by applying a magnetic field and a medium sensitive to areas of magnetic flux leakage.This medium will be attracted,and held,to the part surface(by the flux leakage)and the visual indication of a discontinuity then interpreted by a qualified operator.
Ultrasonic testing can be limited by material thickness and rough surfaces, while magnetic particle testing requires magnetic materials and surface preparation. Radiographic testing exposes workers to radiation, and dye penetrant testing can miss subsurface defects. Eddy current testing is sensitive to material conductivity variations and surface conditions.
Magnetic particle is useful in detecting surface and near surface discontinuities in ferromagnetic material. It is used in foundry control thru manufacturing processes and can be used to detect fatigue and stress cracks in parts that have been in service. A great source of free information can be found through Iowa State's NDT website. Examples of discontinuities that can be found are - linear cracks , linear inclusions , seams , stringers. KThe key is the part must be ferromagnetic , the indications sought must be linear.
No, a stationary charge particle cannot be accelerated in a magnetic field. In order to be affected by a magnetic field, the charged particle must be moving.
A charged particle must be moving in a magnetic field in order to experience a magnetic force. If the particle is stationary, it will not experience a magnetic force.
The magnetic moment of an elementary particle, such as an electron, is a measure of its intrinsic magnetic properties. It describes how strongly the particle interacts with an external magnetic field. This property plays a key role in understanding the behavior of particles in the presence of magnetic fields.

API = American Petroluem Institute NDT = Non-destructive Testing NDT is a process of testing the integrity of a piece of pipe (oil well tubing or casing) that does not damage the material in any way. There is wide range of ways to perform NDT evaluations on tubing and casing products.
The best method for detecting defects in welds is Magnetic Particle. You can also use Fluorescent penatrent, and x-ray but they can be time consuming and often unreliable.

Eddy current testing can be carried out on all the metals provided the metals should be able to conduct the current. No need that it should have magnetic property. Magnetic praticle testing can be carried out only on ferromagentic materials since it works on magnetic permeabiltiy principle. Materials which has poor magnetic permeability is not able to test with MPI. This is very simple answer.
NDT Training and Testing Center in Chennai focuses on handing over tremendous education in a number of NDT methods. Non Destructive testing courses in Chennai, The institute presents each temporary and long-term course, catering to the numerous wishes of college students and professionals. The curriculum covers theoretical knowledge, realistic applications, and industry-specific insights to make certain a well-rounded perception of NDT principles.
The formula to calculate the amperage of a ring in magnetic particle testing is Amperage = Voltage / Resistance, where Voltage is the potential difference across the ring and Resistance is the total resistance of the ring. The amperage determines the magnetic field strength generated by the ring to magnetize the test specimen for detecting any discontinuities.
