DXSG Series Fixed Air Gap Electromagnet: Double-yoke fixed air gap electromagnets have the best rigidity, they can installed vertically or at certain angle, and the magnetic field is horizontal. This kind of electromagnets are suitable for applications of the situation that requires strict magnetic field gap changes and high magnetic field evenness, such as NMR test, vibration sample magnetometer and so on. The magnetic air gap can be changed through replacing magnetic pole-head. More informations[...]

DXSB Series Electromagnet Features Air gap is double-tuned. Double yokes structure forms closed magnetic circuit, with better rigidity. Magnetic field direction is horizontal. Yoke iron is oriented at a 45°angle, easy to take and put samples. This kind of electromagnet can be used in magnetic materials test, vibrating sample magnetometer, Hall effect studies, magnetoresistance effect research, magnetostriction research, torsion magnetometer, force method magnetometer, magnetic susceptibility[...]
