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 are the disadvantages of various NDT methods?
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.
What is magnetic particle testing in NDT?
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.
How to test a Ruby application effectively?
To test a Ruby application effectively, use tools like RSpec or Minitest to write unit tests for individual components. Also, consider integration testing to check how different parts of the application work together. Use continuous integration tools like Jenkins or Travis CI to automate testing processes. Additionally, perform manual testing to ensure the application functions as expected in real-world scenarios.
Can you tell if gold is real with a magnet?
No, a magnet cannot determine if gold is real because gold is not magnetic. Gold is a non-magnetic metal, so it will not be attracted to a magnet. Other methods, such as acid testing or specific gravity testing, are typically used to determine the authenticity of gold.
What are the demerits of magnetostriction method?
Some demerits of the magnetostriction method include its lower sensitivity compared to other non-destructive testing methods such as eddy current testing, its dependency on the material's magnetic properties, and its limitation in detecting surface defects accurately. Additionally, magnetostriction testing can be influenced by external magnetic fields and may require a skilled operator to interpret the results accurately.
Explain the basic principle of magnetic particle testing?
By changing the permiability of ferromagnetic meterials, surface and near surface discontinuities are traced, is the principle of magnetic particle testing. By changing the permiability of ferromagnetic meterials, surface and near surface discontinuities are traced, is the principle of magnetic particle testing.
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.
What are the non destructive tests for welding?

What are practical errors from cement testing?
practical errors in cement testing
What is the formula to compute the amperage of a ring in magnetic particle testing?
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.
What is mpi?

What is static analysis in testing?
Testing of an Application at the specification or implementation level without execution of that Application.
Which do you think is a better indicator of computer application skillsa written test or a production test?
If you're testing for skills a practical test is always better than a written test.
What web application testing has the fastest service?
There are tons of web application testing services and some of the best ones with the fastest service include Sauce Labs, Going Faster, Oracle Application and User Testing.
