Features: 

* solenoid because of the axial magnetic field is uniform, so suitable for narrow samples, under this premise and the coil magnetic field comparison, can do more high, the volume can be smaller. 

* can be used to study the magnetic field, produced standard judgment, electromagnetic interference simulation experiment, Holzer probe and various magnetometer calibration,biological magnetic field research and the material of the magnetic properties of magnetic shielding effectiveness. 

Solenoid uniformity is good, the appearance of small size, high magnetic field. Can produceAC, DC magnetic field, the current has a good linear relationship with the magnetic field.

The main purposes:

Applicable to all research institute, universities and enterprises do magnetic material ordetection experiment, applied to various materials, electronic, biological, medical, aerospace,chemical, applied physics and other disciplines, its main purpose: to produce standard magnetic field, the study of Holzer probe and various magnetometer calibration, biological magnetic field research and the material of magnetic properties the magnetization and demagnetization, magnetic materials, can also be used as an electromagnet or inductor.
