to exhibit magnetism. for example, permanent magnets are used as compass needles. example of permanent magnets an everyday example of a permanent magnet is a refrigerator magnet. the image below shows the magnetic field produced by a bar magnet. the magnetic field is the sphere of influence of...
The definition of weighted average differences P of electronegativities and Q of atomic pseudoradii between rare earth and other elements was introduced in respect of rare earth permanent magnet materials. The P,Q values of the materials with good magnetic properties were calculated. These rare eart...
This review deals with the definition and development of hard magnetic materials with special emphasis on more recent developments in this field. After dis... Kirchmayr,H R - 《Journal of Physics D Applied Physics》 被引量: 114发表: 1999年 Applications of superconducting permanent magnets driven...
There is no violation of the energy conservation laws, of the laws of physics, or of the laws of thermodynamics since this is an open system far from equilibrium with its source of potential energy (the magnetic dipole of the permanent magnet), which in turn continuously receives replenishment...
7.The system of claim 1 wherein the two rows of magnets are arranged in a parallel magnet array wherein one row is in a straight line and the second row is staggered by a selected pitch. 8.The system of claim 1 wherein the control system comprises at least one incremental rotational ...
The idea of remote magnetic guiding is developed from the underlying physics of a concept that allows for bijective force generation over the inner volume of magnet systems. This concept can equally be implemented by electro- or permanent magnets. Here, permanent magnets are in the focus because ...
This paper presents a 3D physical model and a magnetic circuit model for an on-chip planar power inductor design that utilizes a permanent magnet to double the saturation current. The presented power inductor is named the permanent magnet on-chip power inductor (PMOI). The power inductor without...
