Before the discovery of the neodymium magnet, the strongest permanent ... a measure of a magnet’s resistance to other strong magnetic fields,” explains Sagawa. “However, I knew that if ...

That's an electrical current that forms in the copper, in response to the moving magnetic field of the falling neodymium magnet. That eddy current produces a magnetic field of its own. The two ...

Getting a magnetic field to balance on another magnetic ... [EmmaSong] was able to balance a high density neodymium magnet in midair. He pulled off this tricky project using a set of four coils ...

This study showed that a magnetic field applied to a magnet that has not undergone ... One benefit of this technique is the ability to analyze crystal structures in neodymium magnets containing Dy.

Advanced materials with finely tuned electric and magnetic properties are the ... electron microscope to investigate the magnetic fields of neodymium-iron-boron (Nd-Fe-B) permanent magnets ...

The magnets made by the magnetic field printer can be considered Halbach arrays. Everything begins with a blank Neodymium magnet. We’re all familiar with CNC technology, so we’ll focus on the ...

Scientists have discovered a material to help them extract critical components needed in electric vehicle batteries.  ...
