Magnetic Particle Examination Magnetic particle examination (MT) is a very popular, low-cost method to perform nondestructive examination (NDE) of ferromagnetic material. Ferromagnetic is defined in ASME Section V as “a term applied to materials that can be magnetized or strongly attracted by a magnetic field.” MT is an NDE method that checks for surface discontinuities [...]
How to Determine Polarity of Magnets You might have heard the phrase “opposites attract.” While perhaps not always the best advice for relationships, this cliché is the rule of thumb for magnet polarity. Since we inhabit a giant magnet (Earth), understanding magnet polarity on a small scale will help you understand the larger magnetic field [...]
Rare Earth Permanent Magnet Application Classification based on Operation Principle Rare earth permanent magnet can be classified into five types according to its operational principle, includes Lorentz Force Effect, Ampere’s Circuital Law, Faraday’s Law of Electromagnetic Induction, Coulomb’s Law for Magnetism and other magnetic effects. Actually, each operational principle has extremely widespread application area. Lorentz Force [...]
