The pursuit of achieving pure sound is an exceedingly tricky undertaking. It can take a lot of mathematics and testing to combat one of the greatest impediments — magnetic hysteresis distortion. One of the best […]
Motivated to develop a new current sensing technology using the best possible properties of a gap-less magnetic core and a single core construction as in single-core closed loop transducers, Slovenian test and measurement specialist Dewesoft […]
The need to increase the rate of joining electrically conducting components has become critically important in the electric vehicle sector as it is emerging to be the bottleneck of manufacturing, according to Alex O’Farrell, development engineer with Cambridge Vacuum Engineering. As a maker of welding machinery, the UK-based company works close to the subject. In a recent presentation prepared for the 75th International Institute of Welding Annual Assembly & Conference in Tokyo, O’Farrell made his case for electron beam welding technology, highlighted here. […]
Depending on how they interact with magnetic fields, most materials are classified as diamagnetic, paramagnetic, ferromagnetic, ferrimagnetic, or antiferromagnetic. We love the article by Mike Gedeon, customer technical services manager of Materion Performance Alloys and Composites, that explains these different kinds of magnetic properties and related aspects such as magnetic susceptibility. A few highlights follow. […]
Do you know that permanent magnets are behind the action for your detachable keyboard, the pencil that attaches to your tablet, and the wireless charging pad that attaches to your phone? Smart screen covers for phones, tablets, magnetically latching wall-mount security cameras and countless electronic devices in day-to-day life rely on permanent magnets for providing the magnetic attaching mechanism. […]
TV-tuners, laptops, and digital gaming systems all use ferrite beads for filtering frequencies in electronic circuits. A ferrite bead helps minimize interference, generating a cleaner signal. Here’s a brief comparison of the ferrite bead vs. […]
Remanence, coercivity and permeability are fundamental concepts to understanding the magnetic properties of permanent magnets. There is much to know about them and other key aspects of magnetics technology that is important for sophisticated design […]
