In the world of neodymium magnets, N42 stands as a symbol of remarkable strength and magnetic prowess. In this article, we’ll explore the world of N42 neodymium magnet

N42 Neodymium Magnet Meaning: What Does N42 Neodymium Magnet Mean?

An “N42 magnet” refers to a particular grade of neodymium magnet. Neodymium magnets are classified into various grades, each designated by an “N” followed by a two-digit number, such as N42. In the case of N42 magnets:

“N” stands for neodymium, a rare-earth element known for its strong magnetic properties.
“42” represents the grade or strength of the magnet. Specifically, N42 magnets are known for their magnetic strength, with N42 being one of the mid-range grades in terms of magnetic power.

N42 Magnet Strength: N42 Magnet Pull Strength

On average, an N42 magnet of standard size can have a pull force ranging from a few pounds to over 20 pounds. The actual weight a specific N42 magnet can hold depends on several factors. Here are some general guidelines:

  • Surface Material: The type of material the magnet is attracted to also affects its holding capacity. For example, an N42 magnet will typically hold more weight when attached to a ferrous (iron-containing) material than when attached to a non-ferrous material like aluminum or wood.
  • Contact Area: The larger the contact area between the magnet and the object it’s attracting, the more weight it can hold. Smaller contact areas may result in reduced holding capacity.
  • Quality and Manufacturing: The quality and consistency of the neodymium magnet can vary between manufacturers. High-quality magnets with precise manufacturing processes tend to have more reliable and consistent holding capacities.

 

Magnet N42 vs N52:Difference Between N42 and N52 Magnets

N42 and N52 are both common grades of neodymium magnets, and their characteristics differ significantly. Here’s a comparison between N42 and N52 magnets, including their remanence (Br), coercive force (Hc), maximum energy product ((BH)max), and maximum operating temperature:

  • Remanence (Br):
    N42 Magnets: Remanence typically ranges from approximately 12.8 to 13.2 kilogauss (kG) or 1280 to 1320 milliteslas (mT).
    N52 Magnets: Remanence is significantly higher, ranging from about 14.4 to 14.8 kG or 1440 to 1480 mT.
  • Coercive Force (Hc):
    N42 Magnets: Coercive force is typically around 11.0 to 11.6 kilo-oersteds (kOe).
    N52 Magnets: Coercive force is generally higher, ranging from about 12.0 to 12.6 kOe.
  • Maximum Energy Product ((BH)max):
    N42 Magnets: The maximum energy product typically falls within the range of 40 to 43 mega-gauss-oersteds (MGOe).
    N52 Magnets: These magnets have a significantly higher (BH)max, typically ranging from 49 to 52 MGOe. This is a crucial indicator of their greater magnetic strength.
  • Maximum Operating Temperature:
    N42 Magnets: The maximum recommended operating temperature for N42 magnets is usually around 80 to 100 degrees Celsius (176 to 212 degrees Fahrenheit).
    N52 Magnets: These magnets have a slightly lower maximum operating temperature, typically around 70 to 80 degrees Celsius (158 to 176 degrees Fahrenheit).

 

In summary, N52 magnets have higher remanence, coercive force, and maximum energy product compared to N42 magnets. This makes N52 magnets significantly stronger in terms of magnetic performance. However, N52 magnets are more susceptible to temperature-induced demagnetization, so they have a slightly lower maximum operating temperature compared to N42 magnets. The choice between these grades depends on the specific application’s requirements for magnetic strength, operating conditions, and budget considerations.

N35 vs N42 Magnet: What Is the Difference Between N42 and N35 Magnets?

The following detailed data provide a more precise understanding of the differences between these two magnet grades. The choice between N42 and N35 depends on your specific application requirements.

N42 Neodymium Magnet:

  • Coercive Force (Hc): Typically around 12.4-12.7 kOe (kiloOersteds).
  • Remanence (Br): Generally ranges from 12.4-12.8 kG (kiloGauss).
  • Maximum Energy Product (BHmax): Typically in the range of 40-42 MGOe (MegaGauss Oersteds).
  • Maximum Operating Temperature: Typically around 80°C (176°F).

 

N35 Neodymium Magnet:

  • Coercive Force (Hc): Typically around 10.9-11.4 kOe (kiloOersteds).
  • Remanence (Br): Generally ranges from 11.7-12.1 kG (kiloGauss).
  • Maximum Energy Product (BHmax): Typically in the range of 33-35 MGOe (MegaGauss Oersteds).
  • Maximum Operating Temperature: Typically around 80°C (176°F).
