The purpose of this study was to clarify what effect electromagnetic fields had on living bodies. We experimented on Xenopus laevis as an individual. We compared the lengths of tails of frogs exposed to the electromagnetic field (20 kHz) of an IH cooker and a Merritt coil to the tail lengths of sham-exposure frogs. We experimented by changing the exposure time and strength of the electromagnetic field. The results for the present study revealed that an increase in the total daily exposure of Xenopus laevis to an electromagnetic field will speed up metamorphosis.
