The 50 Hz (10 mT) sinusoidal magnetic field: effects on stress-related behavior of rats.
Korpinar MA, Kalkan MT, Tuncel H. · 2012
View Original AbstractRats exposed to a 50 Hz, 10 mT magnetic field for 21 days showed significantly more anxiety-related behavior but no change in activity or exploration.
Plain English Summary
Anxiety and stress-related behavioral changes were investigated by elevated plus-maze and hole-board systems. In the elevated plus-maze, exposed rats spent proportionally less time on open arms than control rats (0.12±0.08 versus 0.34±0.18, p <0.01), while hole-board results showed no statistically significant differences between the two groups.
Why This Matters
Seventy-six young adult male Wistar albino rats were divided into a control group and a magnetic-field group of 38 animals each. Control animals were kept under the same conditions as the exposed group but without exposure to the magnetic field. Researchers tested each animal on the hole-board first, just before the maze test, to separate locomotion and exploration changes from anxiety-related behavior. The results suggest continuous exposure to the magnetic field significantly induces stress and anxiety-related behavior but has no significant effect on activity and exploration activity.

Exposure Context
This study used 10 mT for magnetic fields:
- 500Kx above the Building Biology guideline of 0.2 mG
- 100Kx above the BioInitiative Report recommendation of 1 mG
Building Biology guidelines are practitioner-based limits from real-world assessments. BioInitiative Report recommendations are based on peer-reviewed science. Check Your Exposure to compare your own measurements.
Where This Falls on the Concern Scale
Study Details
The purpose of this study was to investigate the behavioral changes induced by 50 Hz, 10 mT flux density Sinusoidal Magnetic Field (MF).
Seventy-six young adult male Wistar albino rats were used in the study. They were separated into two...
In the hole-board system parameters there were no statistically significant differences between the ...
Our results suggest that after 21 days, a continuous exposure to extremely low frequency of magnetic field (50 Hz, 10 mT) has no significant effect on activity and exploration activity but significantly induces stress and anxiety-related behavior in rats.
