Abstract
The human brain exhibits electrical activity in the form of tiny alternating currents. Using extremely sensitive equipment it is possible to monitor these currents from voltages present at the skin surface of the head and it has been established that different frequencies correspond to some extent with the subject’s mood or mental state.An alternating magnetic field induces electrical currents in conductive material
within range and brain tissue is such a conductor. So we have made a device called “Mood Changer” which generates magnetic field of some specific frequencies in order to change the brain states.The idea is quite simple. Firstly, there is a frequency generator in it which uses PIC microcontroller to generate digital sine wave at four different frequencies.Then,
the wave is become smooth and amplifies and finally magnetic field generates. This magnetic field, according to above phenomenon,changes the mental states.
