What does n50 mean in magnets?
The difference between n35 and n50 magnets is the maximum strength that they can be magnetized to. The basic principle is that the higher the number the stronger the magnet. N35 is, therefore, the weakest and n50 the strongest of the neodymium magnets.
What does the N number mean in magnets?
The grade, or “N rating” of the magnet refers to the Maximum Energy Product of the material that the magnet is made from. It refers to the maximum strength that the material can be magnetized to.
What is the difference between N35 or N52 magnets?
NIB magnets come in different grades, which correspond to the strength of their magnetic fields, ranging from N35 (weakest and least expensive) to N52 (strongest, most expensive and more brittle). An N52 magnet is approximately 50% stronger than an N35 magnet (52/35 = 1.49).
Is neodymium heavy?
Another important use of neodymium is as a component in the alloys used to make high-strength neodymium magnets—powerful permanent magnets….

Why is neodymium malleable?
Neodymium is a ductile and malleable silvery white metal. It oxidizes readily in air to form an oxide, Nd2O3, which easily spalls, exposing the metal to further oxidation….neodymium.

What is stronger N42 or N52?
You can get the same strength as an N52 magnet by using a slightly larger N42 magnet. 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.
How strong are N50 magnets?

How many Gauss is a fridge magnet?
100 gauss
A refrigerator magnet is 100 gauss, a strong refrigerator magnet. The typical strength of the Earth’s magnetic field at its surface is around a half a gauss. So those are everyday units of magnetic fields. There are 10,000 gauss in one tesla.
How strong is N52 magnets?
Grade N42 magnets have a Br of 13,200 Gauss, while N52 magnets can be as high as 14,800 Gauss. See our Specs page for more Br values for various neodymium magnet grades. The Surface Field is the strength of the magnetic field measured right at the surface of the magnet.
Can neodymium magnets damage cell phones?
Will the magnet hurt my phone? We still get asked every day — “Will a magnet hurt my phone?” The simple answer is “NO.” Apple iPhone and Android devices use NAND flash memory, which is immune to magnets. Even the strong Neodymium magnets we use for our cases are only a fraction of the size and power he uses.
