A device for generation of electromagnetic fields of extremely low frequency.
A new device for generation of electromagnetic fields at extra low frequencies, to be used in fracture treatment, is described. The device involves a coil and a battery powered noise-generator. An alternating magnetic field of 4 X 10(-4) T (4 Gauss) (RMS value) with a frequency range 1-1000 Hz is generated. Results from a controlled randomized study of fresh fractures have shown significant differences (p less than 0.01) between the treated group and the control group. The results are encouraging and motivate further investigations with this method.
