Abstract
In this paper, the design parameters for the magnetic field source at extremely low frequency are proposed. This facility can be used fur in vivo experiments with small animals to investigate biological response to the driving magnetic fields. In case that the exposed animals are motionless, the animals may be affected by the directivity of driving field. To avoid this effect, a 2-axis ELF magnetic field driving apparatus was designed. The optimum location and number of turns of each coil were obtained by numerical analysis. Applying these data to the MATLAB code(for computation), the magnetic field distribution was obtained. The calculation result fur a well-designed facility showed that the space in which the amplitude of the magnetic field lies within the 95 % of the magnetic field distribution was more than 60 % of each axis length.
