Magnetized plasma

This image went viral on the Internet—a joke by Japanese scientists, where a U-shaped magnet was added to a photo of solar prominence. The image was named “Magnetic current”:

магнитный ток

And this is a photo from our laboratory in 2012:

A discharge occurs between an insulated rod electrode (on the left) and a hard-alloy plate T15K6 of a turning tool placed on a metal table. The table is earthed, alongside with the second electrode.

The discharge always occurs over the longest possible trajectory, as confirmed by the photo below:

At first we called this photo “Magnetic current”, too. Such a long discharge at the commercial frequency of 50 Hz was achieved with a specially built plasma generator. Voltage between electrodes is 1,500 V, amperage measured by current clamps is around 1.2 A. Height of an “arc” is about 40 cm. Ionization is typical for plasma, so we decided to use the “magnetic plasma” term, with “magnetic current” meaning a current of corresponding carriers in leads.

The tendency of a magnetic arc towards lengthening can be used to make simplest plasma torches, as shown in the following photo:

Here one of the electrodes is located below the bottom opening of a pipe, the vertical pipe serving as both the frame and the second electrode. A discharge bridges to the upper edge of the pipe. Length of a discharge depends on both supplied energy and a pipe’s length and diameter. If the pipe’s size does not match the amount of supplied energy, discharge does not bridge. As in arc plasma torches, the discharge becomes more stable in presence of water steam. One is inclined to say that plasma is the fourth state of water. The fourth photo shows an electrode touching water surface.

A magnetic current discharge occurs when steam is present over the water surface, and in the water itself. We can see that one electrode is deeply submerged in the water, and another may be located near the water surface, as shown on the photo, or be partially submerged. In both cases, the upper electrode immediately burns and melts, regardless of its material. The main material property which allows this occurrence is electrical conductivity. If both electrodes are fully submerged, interaction between them is minimal. Thus magnetic plasma revealed itself by ionization and glow. But its main property is its ability to impact matter state, development of thermal processes, and, as we surmise, chemical reactions, while remaining invisible.

By creating a device, which places water, magnetic plasma and a heat source in one enclosed space, we can get more desirable results from processes that involve water.

Our project plan includes development and production of induction water heater, steam generator, gas generator and disperser. The first two devices have effectively achieved the stage of practical implementation. The development of the rest continues.

The listed devices work on the basis of the method of short-circuiting powerful (above 3,500 A) alternating currents. When currents of such magnitude occur in secondary pipe coils of an induction unit, a stable magnetodynamic plasma discharge occurs—low-temperature plasma. Use of this new discharge type allows to develop various devices, in which energy is transformed from one type to another with the maximum possible coefficient of performance. For example, during transformation of electric energy to heat in presence of B-Plasma, this coefficient achieves 98% or more.
Concentration of low-temperature magnetic plasma significantly impacts matter reaction to normal energy deposition, with all other conditions being equal. For instance, water turns to steam without boiling. This was determined by the authors and used for creating their induction steam generator. Further increase of heating temperature at the same concentration of B-Plasma results in molecular dissociation of water into hydrogen and oxygen. At the current moment, the authors are working on examining methods of reliably controlling this process, which may lead to development of simple induction water gas (synthetic gas) generators. We assume that this method of synthetic gas production will be the cheapest of all currently known methods and will allow to design and produce competitive gas generators.

Thermal machines are the simplest devices in which the use of low-temperature plasma produces results noticeable in simple tests and experiments. The prospective uses of this invention in (chemical) conversion processes are much more difficult to imagine. This will require a deep theoretical underpinning for the process of low-temperature magnetic plasma discharge, and appropriate resources for financing its development.
