Measuring Permanent Magnets Properties

Measuring Permanent Magnets Properties with Vibrating Sample Magnetometer Vibrating Sample Magnetometers (VSMs) are the most commonly employed tool for properties measurement of permanent magnet materials. They can be applied to magnet powder, thin films, anisotropic materials, magnetic recording materials, single crystals and liquid, etc.. They also allow for a broad temperature range from 4 K [...]

  • Magnetic Induction B and Magnetic Polarization J

Magnetic Induction B and Magnetic Polarization J

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 [...]

  • Hysteresis Curve and Intrinsic Demagnetization Curve (B-H Curve and J-H Curve)

Hysteresis Curve and Intrinsic Demagnetization Curve (B-H Curve and J-H Curve)

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 [...]

  • How Are Samarium Cobalt Magnets Made

How Are Samarium Cobalt Magnets Made

How Are Samarium Cobalt Magnets Made SmCo magnets are rare earth magnets with high magnetic energy product and extremely low-temperature coefficient. Its maximum operating temperature can reach 350°C. When working at a temperature above 180℃, its maximum magnetic energy product (BHmax), coercivity, temperature stability, and chemical stability all exceed those of the NdFeB magnet. But [...]

Handling Neodymium Magnets Safety Precaution

Handling Neodymium Magnets Safety Precaution With high intrinsic coercive force (Hci) over 12,000 Oe and maximum energy product ((BH)max) between 27-52 MGOe, neodymium magnets have the greatest strength among all available permanent magnet materials (>7 times stronger than ceramic magnets) as they are extremely resistant to demagnetization and have high saturation of magnetization. The magnetization [...]

  • Select Material Grades for Neodymium Magnets

Select Material Grades for Neodymium Magnets

Select Material Grades for Neodymium Magnets When you are trying to figure out which neodymium magnets to select for your design needs, you would always see the term “grade” or “N rating” from any supplier or manufacturer. Besides a few other criteria, desired material grade must be defined for a neodymium magnet. So, what does [...]

Magnetic Measurements

Magnetic Measurements Magnetic Measurements For measuring of the fundamental magnetic properties of a material (Br, bHc, iHc, BHmax, demagnetisation curve), Hysteresisgraph or BH-tracker is used. A BH-tracker consists of an iron (usually FeCo) yoke to form a closed circuit, electromagnets to create the demagnetizing field and fluxmeters to determine the demagnetizing field and the materials [...]

Three environmental factors affect function of high temperature resistant magnet

Three environmental factors affect function of high temperature resistant magnet Environment temperature. Since sintered NdFeB has a negative temperature coefficient (αBr<-0.13%/°C, αHcj<-0.6%/°C), the instantaneous maximum temperature and the continued maximum temperature of the operating environment will cause different degrees of demagnetization of the magnet itself. Contains reversible and irreversible, rehabilitative and non-recoverable. Environment humidity. NdFeB [...]
