N52 Grade Magnet - All You Need to Know


N52 grade magnets are a grade of neodymium magnets. They are extremely strong magnets and as such have numerous merits in various industries. N52 magnets are generally considered to be the strongest grade of neodymium magnets readily available. There is a whole lot to learn about N52 grade magnets. Read on to learn more about these special magnets and their unique applications.

What does "N52" Mean?

You're probably wondering why some neodymium magnets are graded as "N52" while others are not. "N52" is the grade assigned to neodymium magnets with an energy product of 52 MGOe. "N52" represents the strength of the magnet. There are other N ratings of neodymium magnets. Some of which are N35, N38, N42, N45, and N48. A higher grade number indicates a higher magnetic strength. N52 magnets are the strongest neodymium magnets you'll come across. For this reason, they are more expensive than other grades of magnets.

Advantages of N52 Magnet over Other Grade Magnet

Just as we mention above, there are various grades of neodymium magnets available on the market. However, N52 grade magnets — for obvious reasons — stand out among others. Here are some of the properties of N52 magnets which give them a higher competitive edge over other grade magnets.


N52 grade magnets have remarkable strength in comparison with other grade magnets. They are used in applications that require great magnetic strength since they can provide a much greater magnetic field. The magnetic strength of N52 magnets is almost 20% more than that of N42 magnets and over 50 % more than that of N35 magnets.


N52 grade magnets are more versatile than other grades because of their high magnetic strength. They can be employed in various challenging tasks that other grade magnets may not be suitable for. N52 magnets can be used for both DIY tasks and industrial tasks.


N52 grade magnets are more efficient than other grades of magnets. This is because they have greater magnetic strength. Small sizes of N52 grade magnets can be more efficient than larger sizes of other grade magnets.


Neodymium magnets are generally durable. Their magnetic strength decreases by 1 % in 10 years. It can take as many as 100 years for you to notice a change in the strength of N52-grade magnets.

Applications of N52 Grade Magnets

Lifting Ferrous Objects

N52 grade magnets are used as lifting machinery. Due to their magnetic strength, they are used in the engineering industry to lift heavy ferrous objects. Even small-sized N52 grade magnets can be used to make machines for this purpose.

DIY Projects

N52 grade magnets can be used in various DIY projects. They can be used to hang pictures, keep fixtures in place, and make drawer closures. Since N52 grade magnets can support a large weight, they can also be used to hang artworks of varying sizes. Further Reading: 18 Neodymium Magnet DIY Tricks And Hacks

Magnetic Separation

N52 magnets are commonly used as magnetic separators. They can be used to remove ferrous contaminants in various industries. This grade of magnets is particularly useful in manufacturing processes that require a high level of purity. Further Reading: Magnets Used in Magnetic Separators

MRI Scanner

Magnetic resonance imaging (MRI) scanners require strong magnets that can create a large magnetic field. N52-grade magnets are perfect for MRI scanners. MRI scanners provide detailed images of the internal structures of the body. They are needed for the accurate diagnosis of various diseases.

Jewelry Clasps

N52 grade magnets with a diameter of as little as 5 mm are effective as jewelry clasps. They provide a strong hold when used in making jewelry clasps.

Audio Equipment

N52 grade magnets are commonly used in audio equipment such as microphones, headphones, and speakers. The magnets provide a strong magnetic field that makes it possible for electrical energy to be converted to mechanical energy and vice versa.


N52 grade magnets can be used in a type of transportation known as magnetic levitation. Magnetic levitation involves suspending an object by strong magnetic fields alone. The magnets provide magnetic forces which counteract gravitational forces.

Factors to Consider while Choosing N52 Grade Magnets

Operating Temperature

N52 grade magnets cannot operate at temperatures above 80 °C. It's important to consider this before choosing N52 grade magnets for any application.

Magnetic Force

You must consider the magnetic force required for a particular application before opting for an N52 grade magnet.

Application Field

While choosing an N52 grade magnet, you must pay attention to the specific requirements of the application. It is important to note how these requirements compare with the properties of N52 grade magnets.


N52 magnets are not exactly cheap to purchase. If you must purchase an N52 grade magnet, you should be sure there are no cheaper alternatives.


If you need a permanent magnet with high magnetic strength, N52 grade magnets might be just what you need. These magnets are used in a wide range of applications, such as levitation, magnetic separation, and MRI scanners. Thank you for reading our article and we hope it can be helpful to you.
