What Are Neodymium Magnets?
What Are Neodymium Rare Earth Magnets?
These are not your typical fridge magnets! Neodymium magnets are the strongest permanent magnets readily available and, even if you've never ever become aware of them in the past, you probably utilize them every day. They're sometimes called NdFeB, or Neo magnets, and in spite of being so strong, they're likewise light-weight, which is why they're popular for a wide range of applications. It's hard to believe, however without this kind of rare earth magnet, a lot of the technological advances that have actually occurred over the past few decades would not have been possible!

How neodymium magnets china ?
Really strong. They will amaze you! A 2-gram (0.07 ounce) neodymium magnet that determines 8 millimeters (0.315 inches) in size and 5 millimeters (0.197 inches) long creates a force of over 1700 grams (3.75 pounds). They're so strong that they have replaced other types of magnets in numerous applications. For instance they are over ten times stronger than ceramic magnets, so you may change a ceramic magnet with a much smaller sized neodymium magnet and produce the exact same (or more!) holding force. Be careful-- they're also so strong that even little neodymium magnets can trigger bodily damage. We have actually even heard of bigger neos breaking bones. Handle with care! You can discover more information about the strength in gauss or pounds of holding force of specific magnets using our magnet calculator tools.

What Are Neodymium Magnets Made Of?
Neodymium magnets are made mainly from an alloy of neodymium, iron, and boron. The specific structure can differ depending upon the strength needed and what that magnet is being used for. There are 2 main production types for neodymium magnets: sintered and bonded.

Sintered neodymium magnets are made by heating the alloy components in a heating system, then this mix is cast into molds and cooled to form ingots which are ground into a fine powder and pressed into molds. The molds of powder are sintered to become dense blocks. (Sintering is the process of compacting and forming a solid mass of product by heat or pressure without melting it to the point of liquefaction.) The material is cut into its final shape, covered or plated, and after that magnetized.

Bonded neodymium magnets combine neodymium alloy powder with a polymer binder. The parts are pushed or extruded to make more intricate shapes and magnetization powders than are usually available in sintered magnets.

What Are Neodymium Magnets Used For?
Considering that their development in the early 1980s, a vast array of markets have actually found usages for these super strong magnets. If you're reading this on your computer system, you're utilizing a neodymium magnet right now! Some applications consist of:

Hard disk drives-- A hard disk has tracks and sectors that contain magnetic cells; these cells are allured when information is written to the drive.

Microphones, earphones and loudspeakers-- Current-carrying coils are used with long-term magnets to convert electricity into power that changes the pressure of the surrounding air to create noise.

Dentures-- To keep dentures firmly in place, tiny neodymium magnets are used. In fact, neodymium magnets are utilized in several medical gadgets. Find out more about neodymium magnets in medical applications here.

Door catches-- Industrial and property structures often utilize doors with neodymium magnetic latches.

Magnetic precious jewelry-- Magnetic treatment fashion jewelry is frequently made with neodymium magnets; these magnets are also utilized in bracelet and necklace clasps.

Anti-lock brake sensing units-- If you have anti-lock brakes in your vehicle, they make use of neodymium magnets wrapped inside copper coils in their sensors.
