To compare the effects of a constant and pulsed extremely low frequency magnetic field on body weight and blood glucose in mice.
28 female mice were divided into four groups: group 1) exposed to a constant magnetic field for 20 days, group 2) exposed to constant magnetic field for 10 days, group 3) exposed to a pulsed magnetic field for 20 days, and group 4) exposed to a pulsed magnetic field for 10 days.
| Exposure | Parameters |

Exposure 1:
50 Hz
Exposure duration:
continuous for 10 or 20 days

Exposure 2:
50 Hz
Exposure duration:
continuous for 14 h/day on 10 or 20 days

Animals were divided into the following four groups: i) exposure to a constant magnetic field for 20 days ii) exposure to a constant magnetic field for 10 days iii) exposure to a pulsed magnetic field for 20 days iv) exposure to a pulsed magnetic field for 10 days

Exposure to a constant or pulsed magnetic field for 10 or 20 days did not significantly change the body weight of the mice among the groups. In contrast, the constant magnetic field decreased the blood glucose levels of groups 1 and 2 (122.4 and 110.2 mg/dl) in comparison to groups 3 and 4 (138.1 and 129.2 mg/dl).
