Claim:
1. A Low Field Magnetic Stimulation device comprising: a. a user interface comprising a control; b. a waveform generator in communication with the user interface; c. at least one coil; d. a magnetic field generated by a direct conversion by the coil of an electrical waveform generated by the waveform generator; and e. non-transitory computer-readable media encoded with a software module including a command executable by a processor that receives an input at the user interface, the input comprising: an intrinsic frequency of the subject within an EEG band, or a Q-factor of the intrinsic frequency of the subject within the EEG band; and a first direction of moving the intrinsic frequency of the subject up or down within the EEG band, or a second direction of moving the Q-factor of the intrinsic frequency of the subject up or down within the EEG band, and adjusts the electrical waveform and thereby the magnetic field based on the input, the adjustment comprising: generating, in the magnetic field, a first frequency in an EEG band that is higher than an intrinsic frequency in the EEG band of the subject, when the first direction is up; generating, in the magnetic field, a second frequency in the EEG band that is lower than the intrinsic frequency in the EEG band of the subject, when the first direction is down; generating, in the magnetic field, a first target frequency in the EEG band of the subject, when the second direction is up; generating, in the magnetic field, a second target frequency in the EEG band of the subject, when the second direction is down; or generating, in the magnetic field, a plurality of frequencies, when the second direction is down, wherein each of the plurality of frequencies is within a pre-determined frequency range, wherein at least one of (a) a strength of the magnetic field is more than 0 Gauss and less than about 100 Gauss, (b) the magnetic field is uniform, (c) the magnetic field is configured to target the whole brain, and (d) the waveform has a frequency of at least about 1 Hz and less than about 100 Hz, wherein the magnetic field is applied close to a head of the subject, and wherein the Q-factor of the intrinsic frequency is the intrinsic frequency within the EEG band divided by a frequency bandwidth comprising frequencies that are within the EEG band and having energy at or above half of the energy at the intrinsic frequency within the EEG band.
