Octupole gradient magnetic field electromagnet, gradient magnetic field generator, electromagnet, magnetic field generator case sharing

A uniform three-step magnetic field is also called an octopole magnetic field. A uniform three-step magnetic field can be expressed as a three-step magnetic field, B "'= G" = constant. In accelerators, it is used for Lando damping. The core magnet forming such a magnetic field shape is an eight-pole magnet. The following is the eight pole gradient magnetic field electromagnet, gradient magnetic field generator, electromagnet, magnetic field generator case sharing

FE-2100RD magnetic distribution automatic measuring instrument space magnetic field distribution measuring instrument Magnet analyzer case sharing

FE-2100RD magnetic distribution automatic measuring instrument space magnetic field distribution measuring instrument Magnet analyzer case sharing

The FE-2100RD space magnetic field distribution measuring instrument is mainly composed of an industrial control computer (measurement software), a motion control system and a data acquisition system. First, a test command is sent through the industrial control computer to control the motion control system to complete the set motion trajectory. At the same time, the data acquisition system synchronously controls the work of the data acquisition system. The data acquisition system collects data in X, Y and Z directions through Hall sensors, and then transmits the data to the industrial control computer for data processing, finally, the three-dimensional magnetic field distribution map is obtained.

Helmholtz coil design case sharing

Helmholtz coil design case sharing

A Helmholtz coil is composed of a pair of identical circular conductor coils. Using a Cartesian coordinate system, the central axes of both circular coils of radius R are coaxial with the z-axis. The z-coordinates of the two circular coils are and, respectively. Each conductor coil carries a current I in the same direction. The range of applications of Helmholtz coils includes canceling the earth's magnetic field, generating a magnetic field for experiments, and applications requiring such a magnetic field.

Development history of magnetic declination measurement equipment for rare earth permanent magnet materials

Development history of magnetic declination measurement equipment for rare earth permanent magnet materials

Hunan Yongyi Technology Co., Ltd. began to research and develop magnetic moment and magnetic declination testing equipment in 2010. In 2011, it cooperated with German matesyGmbH Company to introduce "M-axisStandard magnetic declination measuring equipment" into China. M-axisStandard magnetic declination measuring equipment is an innovative magnetic declination measuring equipment. Its principle is to use magnetoresistive matrix to test the spatial magnetic field distribution of permanent magnets, and to obtain the magnetic moment and magnetic declination of magnets by mathematical calculation, which is different from the traditional coil method.

DC electromagnet case sharing

DC electromagnet case sharing

Electromagnet is a device that is energized to generate electromagnetic. On the outside of the core and its power to match the conductive winding, this through the current of the coil like a magnet with magnetic, it is also called electromagnet (electromagnet). We usually make it into a strip or hoof shape to make the core easier to magnetize.

Measurement method of magnetic declination of permanent magnet

Measurement method of magnetic declination of permanent magnet

With the deepening of the application of permanent magnets, magnetic declination has become an important factor affecting the performance of precision magnetic devices. For example, in precision magnetic levitation devices, if the magnet has a large magnetic declination angle, the rotor and stator of the magnetic levitation bearing will also have a magnetic deviation angle of the same magnitude when they are suspended. The existence of this deviation angle will greatly affect the performance of magnetic levitation, and even cause the magnetic levitation bearing to be unable to suspend normally and stably. The existence of magnetic declination angle will cause adverse effects such as system asymmetry, eccentricity and poor dynamic performance.
