Magnetic Particle Inspection For Nondestructive

Disadvantages of the magnetic particle method of nondestructive examination are it is restricted to ferromagnetic materials usually iron andsteel and cannot be used on austenitic stainless steel it is messy most methods need a supply of electricity it is sometimes unclear whether the magnetic field is sufficiently strong to give good indications

Working Principle And Applicationof Magnetic Separation

Because magnetic field strength declines rapidly with the displacement from the magnet magnetic field gradient across the entire volume of magnetic particle solution subjected to separation is usually lower than 100 t m 1 even though a strong neodymium ferrite boron magnet abbreviated as ndfeb magnet and is a permanent magnet with extremely strong remanent magnetization is employed 4445
