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.

What is practical application of magnetic particle testing?
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.

What is the scientific principle behind particle accelators?
particle accelerators work by accelerating a charged particle in a magnetic field where the lines of magnetic flux are such that the particle is accelerated into a circular path. This is so that the force produced by such a motion and magnetic field is perpendicular to both the lines of magnetic flux and the velocity of the particle. The stronger the magnetic field and the faster the particle is moving, the more of a force is required (i.e stronger magnetic field) to keep the particle accelerating. Only a charged particle is affected by a magnetic field so only charged particles can be used inside a particle accelerators (i.e protons and electrons.) neutrons have a charge of zero and are not affected by magnetic fields.
A charged particle moving with a constant velocity enters a magnetic field?
when a charged particle is moving with some velocity it produces some magnetic field. If we place that charged particle in presence of external magnetic field it gets affected by that external field.
What effect does a magnetic field have on a charged particle?
Yes, a moving electron will create a magnetic field. Any moving charge will create a magnetic field around its path of travel. This is the basis for the electromagnetic force, which is one of the four fundamental forces in nature.

Do pneumatic testing is a part of NDT?
No.
What are the non destructive tests for welding?
Magnetic Particle Testing, Ultrasonic Testing, Dye Penetrant, Radiography Testing (x-ray), Visual Inspection
What a api ndt?
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.
Ndt methods of detecting welding defects?
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.

Explain why eddy current testing can be carried out on all the metals whereas magnetic particle testing can only be carried out on ferromagnetic materials?
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.
