- Magnetic fluid Heats the magnetic fluid in the temperature range of about 50 ° C to about 60 ° C. Then, they create a multi-magnetic field in the international space. The heated magnetic fluid is placed in the indicated field. Magnetic fluid will form a liquid wall and will receive an apparent density. Then, on an external magnetic fluid, part of the mechanical mixture is supplied.
- Heating of magnetic fluid to a temperature of 50-60 ° C - 3 - and its stabilization in this interval is carried out by the direct electric heater, electrically connected to the thermostat. 5

- Floating parts of the laptop are interrupted by channel 21 (Fig. 2), where they are unloaded:.: ⁇ to remove the separated particles after
- the copper part that has arrived before the vibration has been removed, which has been tested for the removal of particles, is transferred to channel 20 when it is not in use.
- a heat exchanger 14 is supplied with a heat sink, for example hot water.
- a heat sink for example hot water.
- the volumetric magnetic susceptibility of the magnetic fluid changes in the volume of the receptor.
