Introduction: Bioelectric currents in a patient’s body are possible to act abnormal due to medical problems such as damaged tissues, bones, nerves or blood. Frequency specificity of pulsed electro-magnetic energy is one of the most important factors in obtaining maximum benefits for healing of damaged tissues and pain relief. The waveforms, the available harmonics, and the ON-OFF duty cycle must also be considered. Materials & Methods: Our research has focused on design and implementation of an apparatus to provide extremely low frequency fields in the ELF spectrum of magnetic energy, from a specially designed coil, and presented to the body. The frequencies of specific pulse and sine wave are in the range of 1 Hz to 100 Hz, and each has related biological responses at the cellular level. This system has been referred to as Magnetic Energy Resonance Induction Therapy, or ‘MERIT’. Findings: The output signals have maximum amplitude equal to 2.5v, pulse duty 0.1 to 10ms. The Burst-On Time and Burst off Time of the produced signal was between 1 to 10 second and the total time was between 1 to 999 minute. The user can justify the variable inputs by keyboard and the display system in LCD. Discussion & Conclusion: Application in treatment for electromagnetic fields and its importance rather than conventional methods makes it necessary to have a purposeful program to provide and extent facilities for researchers. The first step in this program is to be designing and producting a reliable, inexpensive and delicate apparatus.
