Magnetic fluids (1983)

Liquid drips.

Drops take a strange shape when interacting with liquid.

Liquid, when exposed to special gloves, flows up following them.

There was a magnet in the gloves.

Definition of magnetic liquid.

Magnetized particles of liquid.

Colloid chemistry helped to create magnetic liquids.

The problem with creating the liquid was that under the influence of a magnetic field the particles stuck together.

Using a surfactant (SAS), each particle was dressed in a protective shell.

Pictures of the behavior of magnetic liquid under the influence of a magnetic field.

Scientists in a laboratory.

Experiment.

A glass ball and a gold ring are lowered into a magnetic liquid.

When exposed to a magnetic field, the ball and the ring float to the surface.

Using a magnetic field, it is possible to create a buoyant force.

This phenomenon became the basis for a new technology for enriching and searching for minerals, from light coal to heavy metals.

Magnetic fluid placed between two polarizing glasses allows one to see the distribution pattern of the magnetic field.

Using these properties of magnetic fluid, one can control the operation of electronic equipment units.

A coil of a loudspeaker's moving system is placed in a magnetic fluid bath. "Radio Engineering" acoustic speakers.

Textile machines.

These machines have many rotating units that require constant lubrication.

These rotating parts can be placed on a magnetic fluid cushion.

Such a bearing can last a very long time.

Magnetic grease can be held at the desired point.

Examples.

It will not splash even at high speeds.

Microorganism cultivation laboratory.

Apparatus for growing beneficial bacteria.

The slightest breach of tightness can completely destroy bacteria.

Magnetic fluid seals reliably protect the object of study from external influences.

Man-made disaster - oil on water.

Footage of animal deaths.

Magnetic fluid can be sprayed on an oil slick and the oil can be collected with a magnetic installation.

Solution of erythrocytes, red blood cells.

Observation of the solution using a microscope.

Current flows through a thin wire, creating a magnetic field.

Some of the erythrocytes are attracted to the wire.

Erythrocytes affected by disease have magnetic properties.

Diagnosis of diseases is possible.

X-ray examination of a patient using magnetic liquids.
