m n&rnxm Xiamen Dexing Magnet Tech. Co., Ltd Helmholtz Coil, homogeneous area is big, and the use of the space is open, also easy to handle. It Can achieve that one-dimensional, two-dimensional and three-dimensional combination of magnetic field, provide ac and dc magnetic field, and electric current and magnetic field can have a good linear relationship. It apply to the institutes, institutions of higher learning and enterprises material or magnetic detection experiment, applied to materials, electronics, biological, medical, aerospace, chemical, applied physics and other subjects, Its main use: produce standard magnetic field; Offset and compensation of the earth's magnetic field, the magnetic environment simulation, judgment of magnetic shielding effect, electromagnetic interference simulation experiment, hall sensor and all kinds of magnetometer calibration, biological magnetic field research and the study of the magnetic properties of the material. Helmholtz coil consists of one couple the same round conducting coils. The center axis of these two round coils with R radius is the same as Z axis. The distance between these two coils is h=R. The number of turns of these two coils is the same, and each coil has homodromous current I. The value of current has good linear relation with magnetic field value. 3.

厦门盈德兴磁电科技有限公司 Xiamen Dexing Magnet Tech. Co., Ltd One-dimensional coil Feature: The space of magnetic field is wide. The direction of magnetic field is horizontal or vertical. It could achieve a rather high magnetic field. The highest magnetic field could reach 10000Gs. It could be used for standard magnetic field, calibration of hall probe and magnetometer, the study of biological magnetic field and analysis of object performance. Two-dimensional coil Feature: The space of magnetic field is wide. Generally the magnetic field is X or Z. The magnetic field these two axis could reach 100Gs at the...

厦门盈德兴磁电科技有限公司 Xiamen Dexing Magnet Tech. Co., Ltd Three-dimensional coil Features: The magnetic field could realize the magnetic field in X, Y Z there direction. Generally, the magnetic field of each axis is low, which is especially suitable for standard magnetic field, the counteract and compensation of earth magnetic field, the simulation of earth magnetic field surrounding, judge of magnetic field shield, the simulating experiment of electromagnetic interference, calibration of hall probe and magnetometer, the study of biological magnetic field and analysis of object performance. Square coil...
