An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the canter of the coil. The magnetic field disappears when the current is turned off. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet. The DC Electromagnet System is designed by our company are most advanced in its specifications and can undertake various tests needed by researchers. The DC Electromagnet system is true bipolar and works in four quadrants just by simple analogue signal + 10V.
