Magnetic Induction B and Magnetic Polarization J Practice and theory have proved that when a ferromagnetic or ferrimagnetic substance is magnetized in a magnetic field, in addition to the magnetic field in the substance, because the magnetic moments of the atoms of the ferromagnetic substance turn to the direction of the external magnetic field, it generates an additional magnetic field M inside…

Hysteresis Curve and Intrinsic Demagnetization Curve (B-H Curve and J-H Curve) Permanent magnet materials have two notable features, one is that they can be strongly magnetized under the action of an external magnetic field, and the other is hysteresis, that is, the material remains magnetized after the external magnetic field is removed. The relationship between the change of the external…

Factors and Methods Affecting the Performance of NdFeB Magnetic Materials Since the advent of NdFeB permanent magnet materials, it has attracted much attention due to its superior magnetic properties. promote. We generally use remanence, coercive force and maximum energy product to measure the performance of magnetic materials. Remanence Br If the magnet is likened to a sponge, the residual…

Switching From Ferrite Magnets to Rare Earth Magnets

Switching From Ferrite Magnets to Rare Earth Magnets Switching from traditional ferrite magnets to rare earth magnets is no small thing. Magnets are measured by their BHmax score. The higher the number the stronger the magnet. Most traditional ferrite magnets will have a BHmax of no higher than 3.5. A rare earth magnet can have a BHmax of up to 40, more than ten times stronger! Any time that you…

What Exactly Is A “Strong” Magnet?

What Exactly Is A “Strong” Magnet? Aren’t all magnets strong? What exactly makes a magnet “strong?” We reveal this ancient secret on our blog today. All magnets have a specific energy density that can be measured, and not surprisingly, some of these magnets have a greater strength than others. Take your everyday fridge magnet. These magnets can easily hold up small notes or postcards, but it…

Super Strong Neodymium Magnets

Super Strong Neodymium Magnets are found in the commercialization of the highest powerful performance magnets, known as the magnetic king, with a high maximum magnetic energy product (BHmax) higher than the ferrite (Ferrite) 10 times.Mechanical processing properties of its own some very good.Operating temperature up to 200 degrees Celsius.And its hard texture, stable performance, good value for…

Magnet Concept

Am area of the magnet, is the cross sectional areal of the magnet perpendicular to the central flux line, measured in sq.cm. at any point along its length. In design, am is usually considered the area at the neutral section of the magnet.

B Magnet induction, is the magnetic field induced by a field strength, H, at a given point. It is the vector sum, at each point within the…

Nanocomposite Permanent Magnet Materials

Nanocomposite Permanent Magnet Materials

Nanocomposite permanent magnet materials, combining magnetically hard and soft phases in nanoscale, is a new permanent magnetic material. Compared with traditional permanent magnetic material, nanocomposite lowers rare earth content and cost, exhibits high coercivity of hard magnetic phase and high saturation magnetization of soft magnetics phase, upgrades…
