Introduction Increase in alpha band is observed when blood perfusion in frontal area of head decreases. The present study evaluated some changes in the alpha band particularly, alpha-1 of frontal and central areas of the head, when several areas were exposed simultaneously to magnetic field. Materials and Methods Five points of head (F3, F4, Cz, T3, and T4) of twenty healthy male participants were exposed to magnetic fields simultaneously by five separate coils at different frequencies of 45, 17, 10, 5, and 3 Hz, in five separate sessions. The magnetic field intensity was 100 μT at 1.5 cm distance from the coil. At the end, relative powers over these areas in common frequency and alpha-1 bands were evaluated by paired t-test. Results Significant reduction (p<0.05) in alpha-1 band was observed by exposure of local ELF magnetic field at frequencies of higher than 5 Hz in closed-eye. These reductive effects were enormous at 5 and 45 Hz frequency. Conclusion Observed reduction in alpha-1 band may be due to the influence of magnetic field exposure on production centers of alpha band, particularly the thalamus. Hence, i
