title: Magnetic fields and time dependent effects on development.
abstract: Pulsed, extremely-low-frequency electromagnetic fields caused a significant increase in abnormalities in the developing chick embryo. The effect was observed when the field was presented during the first 24 h of incubation; no significant effect was observed with exposure from 24 to 48 h of incubation.
