How is magnet strength rated?

In general, the number indicates the strength of the magnet, measured in Megagauss Oersted (MGOe). If a magnet has a grade of N-42, it has a maximum energy product of 42 MGOe. For every increase of 1, the magnet’s strength increases by about 1%. For example, an N-42 magnet is about 2% stronger than an N-40 magnet.

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. In volume production, N35 is often used if size and weight are not a major consideration as it is less expensive.

What is the strongest grade magnet?


What are the different grades of magnets?

The most common grades of Neodymium magnets are N35, N38, N40, N42, N45, N48, N50, N52, and N55. For Samarium Cobalt (SmCo) Magnets, the BHmax will range from 16 MGOe to 32 MGOe. Again, like neodymium magnets, the higher the number, the stronger the magnet.

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.

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.

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.

Are 2 magnets stronger than 1?

Two magnets together will be slightly less than twice as strong as one magnet. When magnets are stuck entirely together (the south pole of one magnet is connected to the north pole of the other magnet) you can add the magnetic fields together.

What are the 7 magnets?

The main types are:

  • Neodymium iron boron (NdFeB)
  • Samarium cobalt (SmCo)
  • Alnico.
  • Ceramic or ferrite magnets.

How strong is a grade 5 magnet?

Commercially available neodymium magnets range from N35 to N55 grade; the number after the letter ‘N’ represents the magnet’s maximum energy product. So, you guessed it, an N55 grade neodymium magnet is approximately 50% stronger than an N35 magnet of the same size.

What does N mean in magnets?

The N stands for neo, an industry simplification of neodymium. The numbers, however, are more complicated. In general, the number indicates the strength of the magnet, measured in Megagauss Oersted (MGOe). If a magnet has a grade of N-42, it has a maximum energy product of 42 MGOe.

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.

What is the difference between an earth magnet and a regular magnet?

The primary difference being that rare-earth magnets are made from alloys of rare earth elements while other permanent magnets are ferrite or alnico. … In contrast, permanent lifting magnets will use the rare earth magnet for it’s immediate surface strength and high resistance to demagnetization.

How much weight can a n52 magnet hold?

95 LBS

Are all magnets the same strength?

Does the size of a magnet affect its strength? The short answer is yes, but only because the size of a magnet means that there are proportionally more domains that can align and produce a stronger magnetic field than a smaller piece of the same material.

Why are neodymium magnets dangerous?

Neodymium magnets create strong magnetic fields around them, which can interfere with pacemakers, ICDs and other implanted medical devices. This is because many of these devices are made with a feature that deactivates the device in a magnetic field. Keep neodymium magnets away from magnetic media.
