A Helmholtz coil is a device for producing a region of nearly uniform magnetic field, named after the German sicist Hermann von Helmholtz. It consists of two electromagnets on the same axis, carrying an equal electric current in the same direction. Besides creating magnetic fields, Helmholtz coils are also used in scientific apparatus to cancel external magnetic fields, such as the Earth's magnetic field.
Dexinmag Helmholtz coils use DC (direct) current source to produce an AC or DC static magnetic field; There is a good lationship between the current and magnetic field.
Main application:
Generate a standard magnetic field;Offset and compensation of the earth's magnetic field;Geomagnetic environment simulation;Judgment of magnetic shielding effect;Electromagnetic interference simulation experiment;Calibration of Hall probes and various magnetometers;Research on biomagnetic fields;The study of the magnetic properties of matter.
