What is N42SH?

What is N42SH?

N42SH grade is for high temperature applications. Operating temperature: 300 degree F (150 degree C) Much stronger and cheaper than other types of high temp magnets such as SmCo, AlniCo and ceramic magnets. Rare earth magnets are the world’s strongest magnets.

What does N42 mean in magnets?

The grade N42 means a neodymium magnet has a maximum energy product of 42 MGOe. It refers to the maximum magnetic energy that the material can be stored. It can be showed by the magnet’s Demagnetization Curve, or BH Curve – the strongest point is (BH)max.

How strong is an N42 magnet?

Grade N42 magnets have a Br of 13,200 Gauss, while N52 magnets can be as high as 14,800 Gauss.

What is the difference between N42 and N52 magnets?

N50 and N52 magnets may be stronger, but their maximum working temperature is limited to 60 ℃, or 140°F. Comparatively, N42 neodymium magnets have a maximum working temperature of 80 ℃, or 176°F. This makes them a better choice for applications where higher working temperatures are involved.

What’s the difference between N42 and N52 magnets?

How strong is a tesla magnet?

The tesla is used as the unit of measurement for very strong magnetic fields and is the International System of Units (SI) standard, while the gauss (G) is commonly used for weaker magnetic fields. The determination for the unit of measurement is one of scale: one tesla is equal to 10,000 gauss.

Why does tesla have 7 MRI?

Defining characteristics. The 7-Tesla MRI provides enhanced detail in cortical imaging, reducing blurring between gray and white matter. “Since the signal to noise ratio is more than doubled, what is invisible or a little ambiguous in a 3-Tesla MRI can be much more clearly defined on the 7-Tesla system,” Dr.

What is the temperature range of n42sh magnets?

This magnet is under grade N42SH, this SH material can be working constantly with temperature higher than 100°. N42SH grade with Br range from 12.9KGs to 13.3KGs, (BH)Max range from 318KJ/m3 to 342KJ/m3.

What is Grade N42 neodymium magnet?

This Grade N42 neodymium magnet is very popular due to its versatile size and excellent magnet strength. One of our best sellers! This neodymium rare earth magnet measures 25 mm (L) x 10 mm (W) x 3 mm (H).

What is n45m neodymium magnet disc?
