3-axis static magnetic field cancellation system

We have been unwittingly exposed to magnetic field. Biological effects due to electromagnetic field exposure has been studied over the past several decades. There has been epidemiological studies and laboratory studies. In the case of laboratory studies, the effect was observed through the cell stimulation of an artificial magnetic field. The used frequency and waveform are various in the cell experiment, but the intensity of the magnetic field is usually around 10G. Intensity of Earth´s magnetic field is about 300-400mG and surrounding electromagnetic fields are various and hard to predict. Although this intensity is not much stronger than artificial magnetic field as 3-4%, but we can´t ignore the effect because every living thing on earth has already adapted for long time ago. In this study, we have designed and implemented the 3-axis static magnetic field generator in order to remove the field in the real-time and kept its intensity less than ±5mG(±0.5uT) using 3 axes Helmholtz coil.
