ABSTRACT Introduction: The aim of this research was to build a variable magnetic field system that can be used in many medical fields such as medical physics, physiology, genetics, biochemistry, anatomy, etc. Materials and methods: In this experimental study the magnetic field was produced between Helmholtz coils by using a variable power supply and signal generator systems. The user can select the desired frequency between 0 Hz (as a static magnetic field) to 300 Hz (as a pulsating magnetic field) with the selector generator. This square wave signal produces magnetic field with intensities from 0 to 8 mT with variations in current. Results: This generator was designed with Helholtz coils which can produce nearly uniform magnetic fields with different frequencies and intensities. This system can simulate fields that general population are subjected to and are concerned about. Conclusion: Calibration with a Hall probe, proved the proper production of a uniform magnetic field of desired intensity and frequency. With the introduction of magnetic fields for treatment procedures and the concerns about their side effects, these generators have become necessary devices in medical research.
