Herm hotz coil (Helmholtz coil) is used to produce standard magnetic field, the wide range of applications, can be used in the hall probe and various magnetometer calibration and compensation of the geomagnetic field, the judgment of magnetic shielding effect, space radiation magnetic field measurement and exclusion and magnetic properties of materials research in areas such as; Space is open, easy to use; Magnetic field has a good linear relationship with power supply current, using the magnetic field homogeneity of space is very wide. IEC61000 - at the same time with 4 to 8 and GB/T17626.8 and GB/T17215-2002 the power of the level 1 and level 2 "ac active watt-hour meter and GB/T15283-94" 0.5, 1 and grade 2 ac watt-hour meter "requirements, according to the need to design and manufacture of one-dimensional, two-dimensional and three-dimensional space combination of magnetic field.

1. The coil magnetic field direction of 90 ° 180 ° / can be adjusted easily

2. The built-in coil subjects test bed

3. The coil can work continuously, the output magnetic field strength stability is good

4. The ac power and dc power supply compatible

Homogeneity of the magnetic field space is very wide

6. A good linear relationship with the current magnetic field
