ELECTROMAGNET SF2

Electromagnet SF2 is a measuring circuits, which makes possible the generation of adequate values of static magnetic fields in air gap between the electromagnet poles, where the measured samples is placed.

Tested sample is situated in measuring head of electromagnet, which is equipped with hall sensor designated for absolute measuring of external magnetic field generated by electromagnet poles.

Furthermore measuring head is equipped with induction sensors designated to measure the induction and tangential component of magnetic field intensity on surface of sample.

The change of magnetic field intensity in the gap of electromagnet is regulated by voltage change supplying the electromagnet. Use of the hall signal in the negative feedback ensures required setting of magnetic field value of electromagnet with high accuracy.

Correct mounting of measured sample in electromagnet requires placing it in the middle of magnetize coil. Therefore it is required symmetrical extending of the both electromagnet poles. Electromagnet SF2 manufactured by us allows setting the one of electromagnet pole in the base position. It is possible due to millimeter scale drawn on the one of pole.
