Characteristics: The uniformity area is big, and the space is open. Generally used in large sample tests, the side length can reach 1m to several meters, and it can be designed as a one-dimensional, two-dimensional, or three-dimensional coil.
Applicable to the standard field, offset and compensation of the earth's magnetic field, the magnetic environment simulation, magnetic shielding effect of the judgment, 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.
