As I mentioned in the previous article, I found it difficult to find saturation curves for common soft magnetic materials by searching the Internet. To help, I decided to share the data I have accumulated over a 20 year period. Here is a link to the data: http://www.fieldp.com/magneticproperties.html/ Values are listed in text format so you can copy [...] I recently had an Internet experience that I have repeated far too often. I needed saturation data for 1008 and 1018 steel for a magnet calculation. These are two of the most common materials used in electromagnets, motors and transformers. The devices are clearly useful — their design involves 100s of thousands of people around the [...] Sheet-beam electron injectors have long been used for industrial processing. Devices for such applications generally have a large cross-section area and relatively low-current density with minimal requirements on beam quality. Their development has been largely empirical. There has been considerable recent interest in sheet electron beams to drive innovative high-frequency, high-power microwave sources. These applications require [...] Recently I received two customer questions about strategies in our thermal programs TDiff (2D) and HeatWave (3D). The first was how to represent the effect of absorbed incident radiation. The assumption is that the user knows the properties of the radiation and the emissivity of the surface. In other words, how do we represent a known [...] |
