The characteristics ：

* produces alternating magnetic field amplitude adjustable frequency of 50~499Hz;

* an electromagnet with a special silicon sheet made of E type magnetic yoke, fixed air gap,pole assembly line at both ends of the excitation package, magnet erect seat placed in the vertical direction, magnetic field;

* the magnetic field in the magnetic field in the center of 10*10mm3 diameter uniformity ofdelta H/H is about 0.01.

The company designed the AC electromagnet can in the given space to generate the alternating magnetic field amplitude adjustable frequency of 50~499Hz.

May carry on the material performance of various experiments under alternating magnetic fieldby using the equipment.

The structure and technical indexes:

1) an electromagnet with a special silicon sheet made of E type magnetic yoke, fixed air gap,pole ends assembled excitation line package, upright seating magnet, magnetic field in the vertical direction. Electromagnet pole face is square 45*45mm2, gap 10mm. 50Hz~499Hz magnetic field can be adjusted continuously, the highest magnetic field up to 1.0T (amplitude value, the same below). 100Hz magnetic field can reach the highest value of 0.5T in the 200Hzis about 0.2T. In the 499Hz field of up to 200~300Gs.

2) uniform magnetic field in the magnetic center district: Phi 10*10mm3 homogeneity Delta H/His about 0.01.

Working time: 3) with a low current density through an electrically operated, line package air cooling, ensure that the magnetic field is rated the highest value, long time workingtemperature is less than 20 DEG c..
