The highest grade of neodymium magnet currently available is N52 . Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium. The temperature ratings are standard (no designation) – M – H – SH – UH – EH.
What is a Grade 8 magnet?
Grade 8 is the strongest ceramic magnet material available (Refer to properties chart below). When making magnetic assemblies with ceramic, it is typically easier for production purposes to magnetize the product after assembly.
Is N52 the strongest magnet?
If you need the highest strength in the smallest possible package at room temperature, grade N52 is the strongest available . ... If you have slightly elevated temperatures, in the 140°F to 176°F range (60°C -80°C), N42 magnets might actually be stronger than N52. This is especially true if your magnet shape is very thin.
What is the 2 strongest magnet?
It is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. Developed independently in 1984 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet available commercially.
How strong is N45 magnet?

How long do N52 magnets last?
How long will a neodymium magnet last? Neodymium magnets are permanent magnets, and lose a fraction of their performance every 100 years if maintained within their optimum working conditions. There are two factors which can shorten a magnet’s lifespan.
Which is stronger N35 or N52 magnet?
An N52 magnet is approximately 50% stronger than an N35 magnet (52/35 = 1.49). In the US, it is typical to find consumer grade magnets in the N40 to N42 range.
How strong is a 1 Tesla magnet?
Measuring Magnetic Strength
One tesla equals 10,000 gauss . Magnometers, gaussmeters or pull-testers are all used to gauge the strength of a magnet.
Many security tags are deactivated in-store with an electromagnetic device. To remove them at home, use a high-powered magnet, such as a hard drive magnet . Place the magnet on a flat surface and lay the tag on top of it with the ink dome or cartridge facing down.
What magnet is stronger than neodymium?
First of all, the Iron Nitride is more powerful than Neodymium magnet (Neodymium magnet). The costs of Nitrogen and Iron are very low compared to rare earth magnets. It is possible to produce Iron Nitride Magnet with production techniques currently used.
Why are neodymium magnets illegal?
That is, until 2012, when the Consumer Product Safety Commission banned them. It turns out that they’re a big hazard to small children , who would often eat them. The balls would attract each other inside the digestive tract, causing massive damage and requiring surgery to remove.
Are Neodymium magnets illegal?
As of January 2017, many brands of magnet spheres including Zen Magnets have resumed the sale of small neodymium magnet spheres following a successful appeal by Zen Magnets in the Tenth Circuit US Court of Appeals which vacated the 2012 CPSC regulation banning these products and thereby rendered the sale of small ...
Does magnets affect human body?
Although they have been used in various diagnostic devices in the health sector and as therapeutic tools, magnets are potentially harmful to the body and pose increased risk of accident.
What is the highest grade neodymium magnet?
The highest grade of neodymium magnet currently available is N52 . Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium.
How strong is 1000 gauss magnet?
A rating of 1,000 gauss resistance is equal to about 80,000 A/m .
Are Cup magnets stronger?
The magnet inside a steel cup construction of a Mounting Magnet offers more strength than a single magnet does when sticking to a steel surface.
