In some cases, a frequency stimulator that can control a dosage of impulses of various low frequencies of electromagnetic waves, uses a cell phone, a tablet, a laptop, and/or any other suitable devices that produce frequencies and can supply an inductive coil that is installed in a headband of the frequency stimulator in a way to produce a low frequency electromagnetic field with the basic purpose of achieving a positive response to the frequency of the human brain that responds to a programed frequency and adjusts to it, thus creating various states of consciousness in the human head. In some cases, the power source is connected to the headband in which there is the induction coil. In some cases, the height, shape and temporal lasting of the frequency impulses is controlled by software installed in a GSM or another source of power.
