What Are Neodymium Magnets?
What Are Neodymium Rare Earth Magnets?
These are not your typical fridge magnets! Neodymium magnets are the greatest irreversible magnets available and, even if you've never become aware of them in the past, you most likely utilize them every day. They're in some cases called NdFeB, or Neo magnets, and in spite of being so strong, they're also light-weight, which is why they're popular for a wide variety of applications. It's hard to believe, however without this kind of rare earth magnet, many of the technological advances that have taken place over the past couple of decades would not have actually been possible!

How Strong Are Neodymium Magnets?
Very strong. They will impress you! A 2-gram (0.07 ounce) neodymium magnet that determines 8 millimeters (0.315 inches) in diameter and 5 millimeters (0.197 inches) long generates a force of over 1700 grams (3.75 pounds). They're so strong that they have actually replaced other kinds of magnets in lots of applications. For example they are over 10 times more powerful than ceramic magnets, so you may change a ceramic magnet with a much smaller neodymium magnet and generate the exact same (or more!) holding force. Be careful-- they're also so strong that even small neodymium magnets can cause physical damage. We've even become aware of larger neos breaking bones. Manage with care! You can find more details about the strength in gauss or pounds of holding force of specific magnets utilizing our magnet calculator tools.

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

Sintered neodymium magnets are made by warming the alloy elements in a furnace, then this mix is cast into molds and cooled to form ingots which are ground into a great powder and pressed into molds. The molds of powder are sintered to end up being dense blocks. (Sintering is the process of compacting and forming a strong mass of product by heat or pressure without melting it to the point of liquefaction.) The material is cut into its last shape, coated or plated, and then magnetized.

Bonded neodymium magnets combine neodymium alloy powder with a polymer binder. magnet manufacturer in china are pushed or extruded to make more complicated shapes and magnetization powders than are typically available in sintered magnets.

What Are Neodymium Magnets Utilized For?
Considering that their innovation in the early 1980s, a wide range of industries have discovered uses for these extremely strong magnets. If you read this on your computer, you're utilizing a neodymium magnet today! Some applications consist of:

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

Microphones, headphones and speakers-- Current-carrying coils are utilized with long-term magnets to convert electrical energy into mechanical energy that changes the pressure of the surrounding air to create noise.

Dentures-- To keep dentures securely in place, small neodymium magnets are used. Actually, neodymium magnets are used in numerous medical devices. Find out more about neodymium magnets in medical applications here.

Door captures-- Industrial and residential buildings often utilize doors with neodymium magnetic latches.

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

Anti-lock brake sensors-- If you have anti-lock brakes in your cars and truck, they utilize neodymium magnets wrapped inside copper coils in their sensing units.
