For instance a 0. However, a magnet that is 0. An example of a coil would be a motor application where the dynamic fields created by a coil set interact with fields from permanent magnets to create motion. This partial demagnetizing, with an external field is exacerbated when the magnet is required to operate at high temperatures. Both the external field and the elevated temperature conspire to demagnetize the magnet alloy.
A quick review of the table of Neo alloy grades show an increase in operating temperature with an increase in the intrinsic coercive force. The higher the intrinsic coercive force, the better the magnet will withstand external demagnetizing fields. The Intrinsic Coercive Force of a magnet material adds cost and that is why the Hci level should be matched to the application. The most prominent material is dysprosium which is very expensive. Also, by adding materials to the lattice, the effective energy of the Neo alloy is reduced.
This means that high grades of Neo with high operating temperatures are very difficult to manufacture, are expensive or not available.
This is especially true when the magnet experiences high temperatures and demagnetizing fields during operation.

Packaged in a hard-sided foam-padded carrying case, this compact unit includes all needed accessories and can be used to test a complete range of magnet types and configurations.
When a manufacturer suspects that a drilling operation could cause plugs inside a precision brake component, he knows that the resulting damage will be more costly and require greater action than a simple phone call. Like any maintenance supervisor at a busy stamping plant, year manufacturing veteran Mike De Vitt's goal at Radar Industries in Warren, Michigan, is to keep his presses up and running.
When raw materials arrive at a food plant, they can contain many types of contaminants, including metals. Metals find their way into raw materials from the time of harvest through the many material handling processes needed to turn them into a product ready for packaging.
Removal of scrap metal is a vital, constant and costly function faced by plant managers worldwide. Untimely removal of scrap can endanger workers and damage machinery. Ensuring that there is no cross-contamination, coupled with dustless operation were their biggest concerns. How can we help?
