How do you measure the strength of a neodymium magnet?
To determine the strength:
- With a gauss meter, you can take the magnet to an area where no other magnetic objects (such as microwaves and computers) are nearby.
- Place the gauss meter directly on on the surface of one of the magnet’s poles.
- Locate the needle on the gauss meter and find the corresponding heading.
What is the strength of neodymium magnets?
Physical and mechanical properties
| Property | Neodymium | Sm-Co |
|---|---|---|
| Compressive strength (N/mm2) | 1000–1100 | 800–1000 |
| Tensile strength (N/mm2) | 80–90 | 35–40 |
| Vickers hardness (HV) | 500–650 | 400–650 |
| Electrical resistivity (Ω·cm) | (110–170)×10−6 | (50–90)×10−6 |
How strong is a N52 neodymium magnet?
Grade N42 magnets have a Br of 13,200 Gauss, while N52 magnets can be as high as 14,800 Gauss. See our Specs page for more Br values for various neodymium magnet grades. The Surface Field is the strength of the magnetic field measured right at the surface of the magnet.
What is the best grade of neodymium magnets?
N52
The highest grade of neodymium magnet currently available is N52. Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium.
How can you determine the strength of a magnet?
The maximum energy product of a magnet is measured in Mega Gauss Oersteds (MGOe). This is the primary indicator of a magnets ‘strength’. In general, the higher the maximum energy product value, the greater the magnetic field the magnet will generate in a particular application.
What is the strongest grade of neodymium magnets?
What is N35?
N35 magnet is a neodymium magnet grade commonly used by our customers. Its magnetic force can meet the requirements of a large number of our customers, and its price is not too high, so it is used in various industries. N35 magnet is just one of the grades of neodymium magnets.
How is the strength of a neodymium magnet determined?
The strength of neodymium magnets is the result of several factors. The most important is that the tetragonal Nd 2 Fe 14 B crystal structure has exceptionally high uniaxial magnetocrystalline anisotropy ( H A ≈ 7 T – magnetic field strength H in units of A/m versus magnetic moment in A·m 2 ).
What is the yield strength of neodymium in MPA?
Yield strength of Neodymium is 150 MPa. Modulus of Elasticity of Neodymium The Young’s modulus of elasticity of Neodymium is 150 MPa.
Which is the most important use of neodymium?
The most important use for neodymium is in an alloy with iron and boron to make very strong permanent magnets.
What is the modulus of elasticity of neodymium?
Modulus of Elasticity of Neodymium The Young’s modulus of elasticity of Neodymium is 150 MPa.
