Magnix Helmholtz Coil

Manufacturer: MAGNIX Co.,Ltd.
Product name: Helmholtz Coil
It consists of two concentric coils, and can generate a uniform magnetic field over a wider range than a normal coil.Furthermore, by combining not only a single-axis coil but also two-axis or three-axis coils, it is possible to combine the magnetic fields of each axis and control the direction of the generated magnetic field.
Features
Supports specified operating environments such as low and high temperatures
Inspection of magnetic influence on products, equipment, and materials
Calibration of probes, sensors, etc. (for generating standard magnetic fields)
Inspection of magnetic sensors such as Hall ICs and Hall elements, Inspection of magnetic influence on magnetic cards, etc.
Inspection of magnetic reed relays
Can use as equipment for other magnetic-related experiments
Example of production: Large two-axis compound (X, Y) magnetic field generating Helmholtz coil
