What are the specific heat and thermal conductivity of N38SH?

The specific heat capacity of N38SH sintered neodymium iron boron is usually about 460 J/(kg · K), which means that for every 1 ℃ increase in temperature of a 1kg N38SH magnet, approximately 460 joules of heat need to be absorbed.... ...More>>

What does the intrinsic coercivity(Hcj) of a magnet do?

Different from the coercive force, when the reverse magnetic field H = Bc, although the magnetic induction intensity B of the magnet is 0, the magnet does not show magnetic flux to the outside, but the vector sum of the microscopic magnetic dipole moments inside the magnet is often not 0, and also That is to say, at this time, the magnetic polarization of the magnet tends to maintain a large value in the original direction.... ...More>>

Which is higher in intrinsic coercivity UH, H, N, and SH?

According to common industry standards, the intrinsic coercivity of H-grade is ≥ 17 kOe (approximately 1353 kA/m), SH grade is ≥ 20 kOe (approximately 1592 kA/m), and UH grade is ≥ 25 kOe (approximately 1989 kA/m). Therefore, the intrinsic coercivity of the three is ranked as UH>SH>H... ...More>>

Important Considerations When Buy Curved Magnets

Arc magnets (magnetic tiles) are widely used in devices such as brushless motors, permanent magnet motors, fans, and water pumps, but they are typical "non-standard custom parts". Many procurement issues arise not from the price itself, but from incomplete technical information or misunder... ...More>>

What Are Tiny Round (Disc) Magnets?

Tiny round (circle) magnets are magnets with a very small diameter size (usually in the range of a few millimeters or less) and a round shape, It can be made smaller, such as a diameter of about 0.5 mm.... ...More>>
