1. wide application 2. wide uniform area 3.easy to use 4.magnetic field has a good linear relationship with current Helmholtz Coil

Using two same coils with equal radius and turns,arrange them to be coaxial and let their distance be equal to the radius of the coil,this called Helmholtz coil. It can be used to generate magnetic field from extremely weak magnetic to hundreds of Gauss.

Specifications:

Helmholtz Coil
Model	Coil Diameter(mm)	Even magnetic field space(mm)	Magnetic Field Center evenness(^H/H%)	Center Magnetic Field(Oe)
H- 500	500	30×30×30	0.001%	500
H-1000	1000	250×250×250	1.0%	20
H-350	400	60×60×60	0.3%	300

Feature: 

Open space, easy to use, magnetic field has a good linear relationship with current, magnetic field space has a very wide uniform area,which is suitable to generate one-dimensional, two-dimensional and three-dimensional space composite magnetic field.

Application:

 1.to generate standard magnetic field 2.calibration for Hall probes and various magnetometers 3.compensation for earth magnetic field 4.judgement for magnetic shielding effect5. measurement and removement for space radiation magnetic field 6. for magnetic properties 7.study for biomagnetism
