DC magnetic field generating system including:

* high precision constant current source

* high stability of electromagnet

* high precision Gauss meter and digital control software

The magnetic field can be two types of manual and automatic regulation mode, according to user needs to tailor the magnetic field generating curve, such as sine wave, square wave,pulse wave, triangular wave and so on, the magnetic field strength can reach the highestscores of Tesla (need low temperature superconducting), resolution of up to 0.01 Gauss, can continuously run for a long time!
