Our engineering staff frequently fields questions from clients asking about magnetization options for Neodymium Iron Boron, Samarium Cobalt, and Ceramic Block, Ring, Disc, and Arc Magnets. Typical questions include:
We answer these questions and more with two new deliverables: a Magnetization Options Tech Brief, which is available in PDF format, and a new Magnetization Options for Neodymium Iron Boron, Samarium Cobalt, Ceramic Magnets page which offers a slightly more robust treatment of this information.
Our engineers are dedicated to providing technically rich information explaining the complex world of custom engineered magnets and magnetic assemblies. With this said, time and space limitations, combined with a seemingly endless list of potential scenarios means that questions may remain after you finish reading our Tech Briefs. Remember, our engineers are just a click or call away. Feel free to send us your questions or contact us by phone at 1-800-492-7939. We welcome the opportunity to answer your questions and discuss your project in further detail.
We are asked many times about the shelf life of permanent magnets. The simple answer is, no, there is no shelf life; however, as all things go with magnets, it is not that simple...
Breakaway force, holding force, fixturing force – “How can all of these represent the same measurement?” a younger engineer recently inquired. Engineers and non-engineers alike can be puzzled trying to understand some of the commonly used – but potentially misinterpreted - terms related to the concept of a magnet’s pull force...
The maximum operating temperature of a magnet is an important property, but it is simply the point beyond which the magnet will experience an irreversible loss in net magnetization. In actuality, a magnet will lose net magnetization as soon as it starts to heat up. This loss is called “reversible” as it is recovered as soon as the magnet cools back down. While avoiding irreversible loss may seem to be the primary concern, even reversible loss can cause a negative impact on a magnet’s performance because while the magnet does not permanently demagnetize, it may not generate enough field for a given application at a particular operating temperature.
