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 [...]
Customizablem Printable Programmable Smart Magnets Programmable magnets , Smart magnets are here, and their potential could be huge. The company Correlated Magnetics uses advanced printing technology to create what they call Polymagnets, which have custom magnetic fields. The magnets can have multiple north and south poles on a single side, enabling engineers to develop faces [...]
