How Strong Rare Earth Magnets and Widely Use

Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt.
Rare-earth magnets are strong, permanent magnets made from alloys of rare earth elements.Rare earth magnets are also called strong magnets have amazing strength in a very small size.

Until recently, all magnets were made from metal elements or alloys. These materials produced magnets of different strengths.For example:

Ceramic magnets, like the ones used in refrigerator magnets and elementary-school science experiments, contain iron oxide in a ceramic composite. Most ceramic magnets, sometimes known as ferric magnets, aren't particularly strong.

Alnico magnets are made from aluminum, nickel and cobalt. They're stronger than ceramic magnets, but not as strong as the ones that incorporate a class of elements known as rare-earth metals.

Neodymium magnets contain iron, boron and the rare-earth element neodymium.

Samarium cobalt magnets combine cobalt with the rare-earth element samarium. In the past few years, scientists have also discovered magnetic polymers, or plastic magnets. Some of these are flexible and moldable. However, some work only at extremely low temperatures, and others pick up only very lightweight materials, like iron filings.

Above passage, we can know rare earth magnets are magnets composed of alloys of the Lanthanide group of elements. The two Lanthanide elements most prevalent in the production of permanent magnets are Neodymium and Samarium. There are numerous alloy formulations of rare earth magnets covered under many different patents but the most common commercial varieties are Neodymium-Iron-Boron (NdFeB) and Samarium Cobalt (SmCo). Neodymium-Iron-Boron magnets are the most advanced commercialized permanent magnet material available today.

Rare earth magnets have ability to retain their magnetic force indefinitely. The magnetic force of these magnets are only affected by the increased temperature and external magnetic force. These magnets are versatile magnets which are designed for various industrial applications.

Rare earth magnets are widely used as follows:

The metal and steel industry, computer hard drives, Audi speakers , Bicycle dynamos, Fishing Reel brakes, stop motion animation as tie-downs when the use of traditional screw and nut tie-downs is impractical; Diamagnetic levitation experimentation, the study of magnetic field dynamics and superconductor levitation.;Launched roller coaster technology found on roller coaster and other thrill rides.
