N35 vs N45 Magnets

N35 vs N45 Magnets - The Ultimate Comparison

Neodymium magnets are a very unique type of magnet. With the many series’ available, this article focuses on N35 and N45. In this article, you will get to know what they are, and their unique properties will be compared. Let’s delve in.

What is N35 Magnet?

The N35 magnet is a permanent magnet and the very first neodymium magnet in its series. Also, it is a sintered iron magnet. These magnets are also classified ad sintered or bonded. This is mostly based on the process of manufacturing you will be using.

What is N45 Magnets?

The N45 magnet falls into the world of neodymium magnets. They are designed ideally to ensure high temperatures are stabilized. They are also permanent magnets.

Comparing N35 Magnets to N45 Magnets


When boron, cobalt, and neodymium is mixed, you make the N35 magnets. Its chemical setup or formula is Nd2Fe14B. N35 magnets also come with a tetragonal crystalline framework or setup. N45 is also composed of boron, iron, and neodymium mixed.

Coercive Force

N45 magnets’ coercive force is lower compared to N35 at 836 KOe. N35 magnets’ coercive force stands at 868 KOe. This is very high. Due to this, you can easily determine that the magnet can keep its strength for long when in use.

Intrinsic Coercive Force

Both magnets have the same intrinsic coercive force which stands at 955 KOe. However, this force for N35 is mainly linked with its material magnetic features.

Maximum Operating Temperature

The N35 magnet is able to withstand an operating temperature of about 80 °C.This is also the same 80 °C for N45 magnets. Knowing this means you are able to know the conditions under which these magnet types can be used.


Remanence is defined as residual magnetism or induction. Also, it stands for the strength of magnets that go on after the outward magnetic field is gotten rid of.

This will mostly range from 11.7 to 12.2 mT. However, N45 magnets have a wider range, which is from 13.2 to 13.7 mT.

Maximum Energy Product

N35 magnets’ MGOe, or maximum energy product, falls within the range of 263 to 267 kJ. While N45 magents fall within ranges of 345 to 359 kJ.

Sizes and Shapes

N35 magnets can be obtained in various sizes and shapes. Some of them include rods, discs, blocks, cylindrical cubes, rings, assemblies, buttons, bars, spheres, and cups. Also, with N45, the sizes and shapes include disc, block, cube, rod, cylindrical, etc.

Coatings used

Coatings for magnets, especially N magnets, are very important. These layers make it possible for you to enjoy resistance to corrosion, durability, friction values, aesthetics, and enhanced handleability.

Some of the N35 magnet coatings include Teflon, epoxy, gold, zinc, Ni-Cu-Ni, copper, titanium nitrate, and black nickel, while the N45 magnet coatings include nickel, black epoxy, zinc, gold, copper, PTFE, plastic, etc.

Magnetic Strength

N35’s has a very high magnetic strength. However, N45 comes with a much higher magnetic strength compared to N35. These magnets depend on their power mostly, and you can count on N45 to provide highly consistent magnetic fields.

Comparing Major Applications

N35 magnets are used in these areas:

N35 magnets are used in these areas

  • Electric motors or generators: N35 magnets are vital for having magnetic fields set up.
  • Magnetic isolation: In the mining and recycling industries, magnetic isolation, or separation, is very important. It can be used to separate ferrous and non-ferrous substances.
  • Closures: N35 magnets can be used as a bag, cabinet, and purse closures. This results in immovable fastening.
  • Hard Drives: N35 magnets are ideal for aiding reading and writing functions in hard drives. This is done through the write or read head control positioning.
  • Reverberance imaging: These magnets aid in having higher-resolution images generated through very strong magnetic fields.
  • Loudspeakers and headphones: To create the crisp and clear sounds that you hear when you use headphones and loudspeakers, N35 magnets play a vital role.
  • Renewable energy: These magnets are vital in electrical vehicles as well as wind turbines. They also aid in generating clean and renewable energy.
  • Bearings: In magnetic bearings, these magnets can be used for specific positioning as well as frictionless aid.
  • Medical apparatus: Most medical apparatus, such as dental supplies, hearing aids, insulin pumps, and more, have this magnet in them to ensure effective functioning.
