A replicate study using large numbers of animals was conducted to determine if 60 Hz magnetic fields would produce developmental toxicity in rats. Systems used previously for electric field exposures were retrofitted to provide magnetic field exposures to small laboratory animals. Large coils, separated from the rat cages, were energized by computer-controlled function generators providing a relatively pure, 1,000--{micro}T (10 G), 60-Hz, horizontal magnetic field for the high exposure group. Leakage fields to a second system provided a second exposure group with average exposures of 0.61 {micro}T (6.1 mG). Ambient fields within a third (control) system were 0.09 {micro}T (0.9 mG). Replicate experiments were conducted in which female rats were mated, and sperm-positive females were randomly distributed among the three exposure groups: (0.09, 0.61, and 1,000 {micro}T). Pregnant animals were exposed to 60 Hz horizontal magnetic fields for 20 hr/day from mating until very near term, 20 days later.
