Abstract :
We have studied the biological effect of the extremely low frequency (ELF) magnetic fields by using goldfish. The body color changes in the goldfish and changes in the amount of urine were examined. As a result, it found that the amount of urine of the goldfish increased when 50 Hz 62 mT magnetic field was exposed continuously for more than 20 hours and at this time flecks in the scale were observed with light microscope. Furthermore, it found that one of causes which these phenomena appeared was an induced current.
