In this article, we will discuss the properties and applications of n35 magnets. Join us!
Neodymium magnets, also known as NdFeB magnets, are a type of permanent magnet made from an alloy of neodymium, iron, and boron. An “N35 magnet” refers to a specific grade of neodymium magnet. In this case, N35 indicates its magnetic properties, including its material and strength. Here’s what the “N35” designation means:
N: This letter indicates that the magnet is made from neodymium.
35: It represents the maximum energy product of the magnet. The energy product is a measure of the magnet’s strength and is calculated by multiplying the remanence (measured in Gauss or Tesla) by the coercivity (measured in Oersted or Ampere per meter). The maximum energy product is often denoted (BH)max.
Compared to higher-grade magnets like N52, N35 magnets are generally more affordable while still offering respectable magnetic performance. These properties let them play an essential role in various applications that require magnetic functionality with cost constraints. Here are some common applications of N35 neodymium magnets:
- Electronics and Gadgets:
N35 magnets can be found in computer hard drives, disk drives, and other data storage devices for efficient data reading and writing.
- Magnetic Closures:
N35 magnets are used in magnetic closures for bags, purses, jewelry, and clothing accessories. They provide a secure closure mechanism without the need for traditional fasteners like buttons or zippers.
- Crafts and DIY Projects:
N35 magnets are often used in arts and crafts projects, as well as DIY applications. They can be employed in creating magnetic displays, interactive games, and other creative projects.
- Magnetic Toys:
N35 magnets are used in the manufacturing of magnetic toys and educational kits.
Let’s compare N35 and N52 neodymium magnets based on their key magnetic properties: Remanence (Br), Coercive Force (Hc), and Maximum Operating Temperature (Tmax).
- A. Remanence (Br)
N35: The remanence of N35 neodymium magnets is typically around 11.7-12.1 kG (kiloGauss) or 1.17-1.21 Tesla.
N52: The remanence of N52 neodymium magnets is higher, usually ranging from 14.3-14.8 kG or 1.43-1.48 Tesla. This indicates a significantly stronger magnetic field retained by the magnet.
- B. Coercive Force (Hc)
N35: The coercive force of N35 magnets is generally around 10.8-11.2 kOe (kiloOersted) or 860-890 kA/m (kiloAmpere per meter).
N52: N52 magnets exhibit a higher coercive force, typically in the range of 14.3-14.8 kOe or 1138-1174 kA/m. This indicates more excellent resistance to demagnetization.
- C.Max. Energy Product (BH)max
N35:Typically ranges from 33-36 MGOe (MegaGauss Oersted) or 263-286 kJ/m³ (kiloJoule per cubic meter).
N52:Typically ranges from 48-51 MGOe or 382-406 kJ/m³. This signifies a substantially higher energy storage capability compared to N35.
- D. Maximum Operating Temperature (Tmax):
N35: The maximum operating temperature for N35 magnets is generally around 80°C (176°F). Above this temperature, the magnet’s magnetic properties may start to degrade.
N52: N52 magnets typically have a slightly lower maximum operating temperature of around 70-80°C (158-176°F).
In summary, here’s a quick comparison of these properties between N35 and N52 neodymium magnets.
Here’s a breakdown of the properties of both N35 and N50 neodymium magnets:
- A. Remanence (Br)
N35: For N35 magnets, the remanence value is typically around 11.7 – 12.1 kG (kilogauss) or approximately 1.17 – 1.21 T (Tesla).
N50: The remanence of N50 magnets is higher than that of N35 magnets. It’s typically around 14.1 – 14.5 kG or about 1.41 – 1.45 T.
- B. Coercive Force (Hc)
N35: The coercive force is above 11 kOe (kilo-oersteds) or approximately 900 kA/m (kiloampere per meter).
N50: Typically around 10 kOe.
- C. Intrinsic Coercive Force (Hcj):
N35: The intrinsic coercive force for N35 magnets is around 12 kOe.
N50: N50 magnets tend to have a lower intrinsic coercive force, typically around 11 kOe.
- D. Max. Energy Product (BH)max
This property represents the maximum amount of energy that can be stored in a magnetic material and is a crucial indicator of the magnet’s overall strength.
N35: The maximum energy product for N35 magnets is around 33 – 36 MGOe (MegaGauss-Oersteds) or about 263 – 287 kJ/m³ (kilojoule per cubic meter).
N50: N50 magnets have a higher maximum energy product, typically around 48 – 51 MGOe or about 382 – 406 kJ/m³.
- E. Max. Operating Temperature:
This refers to the highest temperature at which the magnet can operate effectively without significant loss of its magnetic properties.
N35: The maximum operating temperature for N35 magnets is around 80°C (176°F).
N50: N50 magnets generally have the same maximum operating temperature, also around 80°C.
