Br Magnetic Question - The magnet I ordered has a Br spec of 12.4 kG - why is the flux density only measuring 3.0 kG? This is best explained through referencing the permanent magnet characteristic of permeance coefficient, which is strictly determined by geometry. In general, longer magnets have greater permeance coefficients. Additionally, a magnet [...]
Neodymium Magnets Falling Slowly Through A Fat-Ass Copper Tube - in Copper, Having A Great Time, How Do They Work?, I Play With Magnets On The Regular So There, Kool, Magnets, Metal, Neato, Physics, Slow, Slow Your Roll Magnet Where You Trying To Go In A Hurry?, Sorcery, That Is A NICE LOOKING PIECE OF [...]
Why does a spherical magnet fall so slowly through an aluminum tube? Charles Platt presents a science demonstration involving magnets that will interest juggalos and non-juggalos alike. magnet aluminum tube To explain the perplexing phenomenon of why a spherical magnet falls so slowly through an aluminum tube, I must refer to the right-handed-corkscrew rule. magnet aluminum tube [...]
Could buckyballs make any metal into a magnet? A layer of carbon can bestow the powers of magnetism. Viviane Richter explains. In a feat of modern day alchemy, scientists have successfully turned non-magnetic metals into magnets. Oscar Cespedes at the University of Leeds and his team published their magnetic recipe in Nature in August. The [...]
Rare Earth elements, largely unknown to the majority of the general public, have become national news in the past decade. The magnet industry has used samarium, neodymium, dysprosium and other rare earths for decades as they are a very important ingredient in magnet design. Many of these magnets have enabled new technologies and are also [...]
Multi-poles Magnet - Multi poles magnetized magnet is more and more popular in different applications, this technology increases the magnetic force, it can be formed into shapes and patterns, which provides a possibility of unique design by improved magnetic circuit.

Rare-earth Consumption Uses in Neodymium Magnets - Rare-earth elements (REEs) are also known as the lanthanide series in the periodic table of elements. They are not particularly rare in terms of abundance, but for many years remained rarely separated from each other due to their similar chemical characteristics. Rare earth elements are widely used in [...]
Neodymium Magnets Handling Guidelines Neodymium Magnets are very strong and powerful. Their magnetic power allows them able to generate some magic effect. They are interesting but are not toys. Their special physical properties determine that they are easy to be damaged in magnetic characteristics and need to be handled with extreme care and precision to [...]
How does a magnet work? Atomic structure Magnetic atom: protons with north and south poles, electrons with north and south poles, and neutrons The way a magnet works is determined by its overall atomic structure. Every atom is made up of negative electrons circling around positive protons and neutrons (called a nucleus), which are effectively [...]
Neodymium Magnet Manufacturing Methods, Sintered Neodymium Iron Boron Magnets, Bonded Neodymium Magnets Sintered Neodymium Iron Boron Magnets: The sintered Neodymium Iron Boron magnet is produced by the OPS (orient-press-sinter) method. A crystalline alloy of Neodymium, Iron, and Boron is ground to a sub-micron powder using a ball mill, then aligned in a strong magnetic field, [...]
