A device for processing polymer compositions by alternating magnetic field is designed as a power amplifier comprising first and second transistors, a solenoid with working and measuring windings, an oscilloscope, and a power supply. The device is equipped with a toroidal driving transformer which primary winding is connected to a sound generator, and the secondary winding - to the base of the first and second bipolar transistors of power amplifier made in the form of a two-step amplification stage, and the working winding of solenoid is made with an external ferrite core and is included between the collectors of first and second bipolar transistors. |
