2. What does the N35, N40, N42, N45, N48, N50, N52 grade mean? Neodymium magnets are graded by the maximum strength they can be magnetized to. The higher the number the stronger the magnet is, however the higher the number the more brittle the magnet becomes as well.
What does n52 mean in magnets?
neodymium magnet grade
What is n50 magnet?
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?
What does the grade or “N number” of a magnet mean? 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?
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. In volume production, N35 is often used if size and weight are not a major consideration as it is less expensive.
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 …
Which magnets are strongest?
The strongest permanent magnets in the world are neodymium (Nd) magnets, they are made from magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure.
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. The temperature ratings are standard (no designation) – M – H – SH – UH – EH.
What is the strongest rare earth magnet?
What is n42 grade magnet?
What does grade n42 magnet mean? The grade N42 means a neodymium magnet has a maximum energy product of 42 MGOe. It refers to the maximum magnetic energy that the material can be stored. It can be showed by the magnet’s Demagnetization Curve, or BH Curve – the strongest point is (BH)max.
Is a thicker magnet stronger?
If we have two magnets made out of the same material and the material is magnetized the same, yet one magnet is thicker than the other, the thicker magnet will be stronger. That’s of course because there is more material there to act on an object out in front of the magnet.
How strong is 1000 gauss magnet?
A rating of 1,000 gauss resistance is equal to about 80,000 A/m. As you can see, the B and H fields aren’t really different so much as they are the same phenomenon seen from different perspectives.
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.
How do you tell how strong a magnet is?
The maximum energy product of a magnet is measured in Mega Gauss Oersteds (MGOe). This is the primary indicator of a magnets ‘strength’. In general, the higher the maximum energy product value, the greater the magnetic field the magnet will generate in a particular application.
Is n35 a strong magnet?
Grade N35 is the lowest grade of strong neodymium magnet on the market, however they are also the least expensive neodymium magnets. In many cases the strongest neodymium magnets (N52 Grade) are not required for your project. Under these circumstances the N35 Neodymium magnets are a great value.
Are n52 magnets dangerous?
Neodymium magnets are not toys. … Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attach to each other through intestinal walls causing serious injuries and even death.
