The Electromagnet Field Control Platform
Introduction of Electromagnet Field Control Platform:
The Electromagnet Field Control Platform integrates high performance bipolar magnet power supply and various double-tuned adjustable air gap electromagnets to form a variable magnetic field platform that can be utilized independently or as the foundation for a user-designed magnetic measurement system. It has wide applications, such as magneto-optical studies, magnetic field annealing, Hall effect studies, susceptibility measurements, magnetic resonance imaging studies, B-H curves, and precision sensor calibration.
Electromagnet Field Control Platform
Configuration
Double-tuned adjustable air gap electromagnet
Bipolar magnet power supply with a built-in gauss meter
A gaussmeter Hall probe
Hall probe holder
Feature
High precision bipolar power supply, high magnetic field stability: the system adopts bipolar constant current power supply, digital control mode. The bipolar output allows rapid uniform magnetic field ramping and field reversal, avoiding discontinuities that occur during zero crossover when using unipolar power supplies. The bipolar output also eliminates the need for current reversal contactors or relays.
Magnetic field automatic control, rapidly reach stable: bipolar constant-current power supply with built-in high-precision Gauss Meter, to form a complete closed-loop control circuit in the power supply, compared with the external Gauss meter, it can control the magnetic field to setting value within less time.
The electromagnets feature continuously adjustable air gaps, allowing rapid air gap changes to suit individual experiments.
The user can select H-or C-type structure electromagnet yoke according to different use environments, easy to put in or take out sample.
