Different Grades of Neodymium Magnets

There are various grades of neodymium magnets, denoted by the letter ‘N’ followed by a number. This number represents the maximum energy product of the magnet, measured in Mega-Gauss-Oersteds (MGOe). The higher the number, the stronger the magnet. Some common grades include N35, N42, N45, and N52.

What is the Strongest Neodymium Magnet?

Die strongest neodymium magnet currently available on the market is the N52 grade. With a maximum energy product of 52 MGOe, it offers the highest magnetic force among all neodymium magnets. However, it’s essential to consider other factors such as size, shape, and temperature when determining the overall strength of a magnet in a specific application.

N52 magnets have the highest magnetic strength among neodymium magnets, providing exceptional performance in various applications. However, they also have a lower maximum operating temperature (usually around 60°C or 140°F) than lower-grade magnets, making them unsuitable for high-temperature environments.

Is N52 the strongest neodymium magnet?

Yes, N52 is considered the strongest neodymium magnet due to its maximum energy product (BH)max rating. N52-grade neodymium magnets are 50% stronger than N35-grade magnets and have a maximum operating temperature of up to 80°C.

Furthermore, N52-grade magnets are highly sought after for their superior magnetic properties, which allow them to withstand high levels of resistance and remain magnetized for longer periods. This makes N52-grade neodymium magnets the preferred choice for many industries and applications that require strong and reliable magnetic power.

Which is stronger N42 or N52 magnet?

The N52 magnet is stronger than the N42 magnet. This is because N52 grade magnet has a higher magnetic energy product than N42 grade. The magnetic energy product of the N52 magnet is typically between 48 and 52 MGOe (Mega-Gauss-Oersteds), while the N42 magnet has a magnetic energy product in the range of 40 to 42 MGOe. Thus, N52 magnets can produce a stronger magnetic field than N42 magnets, resulting in greater holding power and more efficient use in various industrial and commercial applications.

However, due to their higher strength, N52 magnets are also more expensive than N42 magnets, making the latter an attractive option for those seeking high performance at an affordable price.

Which is stronger N50 vs N52 magnet?

The N52 magnets are stronger than the N50 magnets. N52 magnets have a pull force of over 76 lbs, significantly higher than the pull force of N50 magnets. If you need a magnet with an especially strong pull force, the N52 grade is the way to go.

Of course, it’s worth noting that both N50 and N52 magnets are incredibly strong and will likely get the job done in most situations. But if you need the strongest magnet available, you’ll want to opt for N52. Overall, N50 and N52 rare earth neodymium magnets are great for powerful and reliable magnets.

Factors Affecting the Strength of Neodymium Magnets

Magnet Size

The size of a neodymium magnet directly impacts its strength. Generally, larger magnets are more potent than smaller ones, as they have more magnetic material.

Magnet Shape

The shape of a magnet also plays a role in its strength. For example, a disc-shaped magnet may exhibit more force when applied to a flat surface than a cylindrical magnet of the same size.


Temperature can affect the strength of neodymium magnets. These magnets may lose part of their magnetic characteristics when exposed to high temperatures. Always consider the operating temperature range of a magnet when choosing one for your application.

How to Measure Magnet Strength

Maximum Energy Product (BHmax)

The maximum energy product (BHmax) is a crucial parameter used to measure the strength of a magnet. It represents the magnet’s ability to store and release energy. The higher the BHmax, the stronger the magnet.


A Gaussmeter is an instrument used to measure the magnetic flux density of a magnet. By measuring the magnetic field strength at the surface of a magnet, you can determine its overall strength.

Sicherheitsvorkehrungen beim Umgang mit Neodym-Magneten

Neomagnets can be hazardous if not handled with care. Here are some safety precautions to follow when working with these powerful magnets:

  • Keep magnets away from electronic devices, as their strong magnetic fields can cause damage.
  • Avoid placing magnets near credit cards, pacemakers, and other devices sensitive to magnetic fields.
  • Be cautious when handling large magnets, as they can pinch fingers or cause injuries if they snap together suddenly.
  • Always wear protective gloves when handling sharp-edged or large magnets.

How to Care for Your Neodymium Magnets

To maintain the strength and longevity of your neodymium magnets, follow these simple care tips:

  • Store magnets in a cool, dry place away from direct sunlight.
  • Keep magnets away from corrosive substances, such as acids and alkalis.
  • Avoid dropping or hitting magnets, as this can cause them to chip or break.
  • Use a soft cloth to clean the surface of your magnets regularly.


In conclusion, the strongest neodymium magnet currently available is the N52 grade magnet. However, size, shape, and temperature can influence a magnet’s strength. When choosing a neodymium magnet for your specific application, consider these factors and always adhere to safety precautions while handling these powerful magnets.
