The aim of this study was to test whether 60 Hz magnetic fields affect heart rate, respiratory rate, and heart rate variability, or give rise to subjective symptoms in adults and teenagers. The ability of teenagers and adults to perceive exposure to a magnetic field was also compared.
Two volunteer groups of 30 adults and 30 teenagers (>13 years old) were tested. Participants with electromagnetic hypersensitivity who attributed their symptoms to appliances and/or high voltage transmission lines or mobile phones were excluded.

In both adults and teenagers, exposure to a 60 Hz magnetic field had no effects on heart rate, respiratory rate, heart rate variability, or subjective symptoms. Neither adults nor teenagers could perceive the magnetic field. No indication was observed that teenagers perceived the magnetic field better than adults.
The authors conclude that there were no effects of 32 min exposure to a 60 Hz 12.5 µT magnetic field on the variables examined in adults or teenagers.
