Abstract: Producing low frequency magnetic pulses irregularly by changing the magnetic fields [generally, 1 gauss , this apparatus expels rats or harmful insects which are sensitive to the changing of magnetic fields. The AC source is connected to a master oscillator (2) through a diode (D1) and a condensor (C1), and is also connected to the source terminal of octode dividers (4,4') and tetrod divider (5). A condensor (C2) and a variable resistor (VR1) are connected to between two terminals (P1, P2) and source terminals (VCC1, VCC2). The output of master oscillator (2) is connected to an input terminal of octode dividers (4,4'). The controlling terminal (P7, P8) of 4' and P8 of 4 are connected to terminals (P1-3) of tetrode divider (5).
