MGT-15-10 5-13kOe 9.2kGS Rare-Earth Magnet

Structural Characteristics of Rare Earth Magnetic Particles

The atoms of the uncommon earth magnetic powder could have a excessive magnetic moment. Their orbital digital systems comprise many unpaired electrons; in different factors almost all electrons exist in pairs of contrary spins, so their magnetic fields cancel every different out, however in uncommon- factors earth the magnetic fields cancel every different out to a miles lesser diploma many. This is an end result of the unfinished filling of the f-shell, that could comprise as much as seven unpaired electrons. In a magnet, unpaired electrons line up and spin within the identical direction, developing a magnetic field. This offers the cloth a excessive remanence (saturation magnetization Js). The most power density, BH, is proportional to J s 2 , so those substances have the ability to keep big quantities of magnetic power. The power product BH max of a neodymium magnet is about 18 instances the quantity of a "normal" magnet.

Common applications for rare earth magnets include

Computer hard disk drives

Wind turbines

Speakers/headphones

Bicycle generators

MRI scanners

Fishing reel brakes

Permanent magnet motors in wireless tools

High performance AC servo motors

The process

The molten NdFeB alloy is sprayed onto the cooling rollers at a certain speed and instantly solidifies to form a thin strip of 0.02-0.05mm thickness. During the rapid cooling process, Nd2Fe14B structure is formed, and finally the thin strip is broken into powder
