Helmholtz coil is the radius and turns with two identical coil, and its coaxial array equivalent to the distance radius from the coils connected in series. It can use a very weak magnetic field up to several hundred Gs magnetic field, the Earth's magnetic field can be used to offset compensation, and other characteristics of permanent magnet.
     My company specializes in design Helmholtz coil may, in accordance with users of the magnetic field strength, uniform magnetic field of space size and uniformity of grading and other requirements of design, well-designed and calculated precision, producing sophisticated. For the authority of universities and research departments by the use of measurement by the user acclaim.
