Intensity threshold for 60‐hz magnetically induced behavioral changes in rats

Abstract

Experiments were conducted to further investigate the effect of 60‐Hz cyclotron‐resonance exposures on rats performing on a multiple FR‐DRL schedule. The previously reported temporary loss of DRL baseline response, when measured as a function of A.C. magnetic intensity, was found to have a threshold. Utilizing the component of A.C. magnetic intensity parallel to the D.C. field, we report this threshold as (0.27 ± 0.10) × 10⁻⁴ T_rms.
