What about a Electro-Magnet

The electromagnets are mainly used in hysteresis phenomenon research, magnetization coefficient measurement, Hall effect research, CI light experiment, magnetic field annealing, nuclear magnetic resonance, electron paramagnetic resonance, biological research, magnetic measurement, magnetic material orientation, magnetic product magnetization and so on.

The electromagnet of TINDUN^® TM series can be divided into single-yoke or double-yoke electromagnet, fixed air gap and adjustable air gap electromagnet, multi-pole solenoids and various non-standard solenoid designs.
