The present invention relates to a method for producing high energy magnets comprising light and heavy rare earth metals, characterized in that at least one heavy rare earth metal is introduced into the permanent magnet from an ionic liquid containing at least one guanidinium compound by means of ...
A device for generating electrical energy has at least one pair of permanent magnets and at least one coil. They are moved about a pivot axis relative to one another by agitating or shaking. Each coil is disposed between the pole surfaces of the at least one pair of permanent magnets which...

As additional elements M, Al, Ti, V, Cr, Mn, Zr, Hf, Nb, Ta, Mo, Ge, Sb, Sn, Bi, Ni or W may be incorporated. The magnets can be produced through a powder meallurgical process resulting in high magnetic properties, e.g., up to 7 MGOe or higher energy product. 展开 ...
Here, the magnetic potential energy U(r) is positive because χv is less than χs. Magnetic force drives GUVs to the regions with lower magnetic field strength, according to the energy minimum principle. Therefore, the spatial structure of the prototissues can be predicted according to the ...
In addition, it should be mentioned that the use of permanent magnets (iron-boron-neodymium magnets) is cur- rently increasing for renewable energy technologies, especial- ly offshore windmills—so a possibly growing market for the raw material of borate, too, besides taking over the role of ...
Harnessing ultra-low-frequency vibration energy by a rolling-swing electromagnetic energy harvester with counter-rotations unique alternating pole arrangement of magnets is adopted that enhances the output voltage by 2 times as compared to the traditional uniform pole arrangement...

In this paper we have devised an approach to convert gravitational pull of Earth (or any other planetary object) into a useful form of energy (mainly electricity). The main concept is based on drilling the Earth's surface at corner (not at center) and passing a rod through the hole causi...
MEASUREMENT OF THE TOTAL CROSS SECTION FOR SINGLE-ELECTRON TRANSFER IN COLLISIONS OF He$sup +$ WITH He IN THE ENERGY RANGE 2 TO 22 keV. Measurement of the total cross section for electron transfer between a ground-state singly ionized helium atom and a ground-state helium atom has been made...
