Some magnet applications require the use of magnets with multiple poles. Multi-pole magnets are used in motors, linear actuators, hall effect applications, and more . For many years manufacturing multi-pole magnets was not easily accomplished, so many designs used multiple magnets positioned in an assembly to create a multi-pole effect. This is, of course, a
Here’s a great example of an automotive related linear motor application. The magnet in this case is a multi-pole injection molded magnet made from a hybrid neodymium and ferrite blend. The magnet is injection molded directly to a zinc plated steel hub – no gluing or assembly required. The hub is knurled to promote the
In concert with a new strategy for autonomous technologies, the US Navy is launching a research project to develop a system based on a high-temperature superconducting (HTS_ magnetic source with an advanced acoustic generator to detect underwater magnetic influence mines. The Office of Naval Research expects to award one to three contracts priced between $12
How Electric Cars Work: Motors. It has to do with magnetism and the natural interplay between electric fields and magnetic fields. When an electrical circuit closes allowing electrons to move along a wire, those moving electrons generate an electromagnetic field complete with a north and a south pole. When this happens in the presence of
FluxWear, a neuromodulation technology startup located in southern California, demonstrated its first product at the 2022 Consumer Electronics Show in Las Vegas in January. The product, SHIFT, is a wearable neuromodulation device to help people with pain, anxiety or stress to rapidly attain a meditative state. SHIFT is designed to deliver a unique magnetic stimulation
Using proprietary nano-sized magnetic beads with specialized binding capabilities, Veravas, Inc., an early-stage diagnostics company based in Austin, Texas, has created a new development platform for biotech scientists. Researchers can employ it to measure antibodies against any antigen of interest in serum, plasma or saliva. Read the full article on magneticsmag.com
The global neodymium market size is expected to reach USD 3.39 billion by 2028. It is expected to expand at a CAGR of 5.3% from 2021 to 2028. The demand for electrical and electronic products is projected to assist the market growth over the long term. Neodymium-based magnets are used in a variety of consumer
Technology that other vendors couldn’t supply was developed by EAM. Here’s what we did to provide the solution… They had designed a magnetically controlled valve for a line of machines that regulate the flow of anesthetic gas delivered to each patient. Obviously, the performance of these valves is extremely critical. They are subject to stringent
Electric vehicles (EV’s) use Permanent Magnet (PM) motors. Over the next decade, the number of EV’s on the road is expected to grow to more than 250 million! Earlier versions of EV motors were powered by induction motors, which did not use permanent magnets, however newer versions of EV motors are making use of permanent
All materials are defined as being magnetic in that they respond to the application of an applied magnetic field differently to that of air or vacuum. Only selected elements or alloys have useful magnetic properties in engineering applications. Magnetic materials which are easily magnetized and the magnetized are often termed soft. Conversely, those magnetic
