Yes very good. Now lets take a look at the fourth state of matter..plasma:
"Plasma is created by adding energy to a gas so that some of its electrons leave its atoms. This is called ionization. It results in negatively charged electrons, and positively charged ions. Unlike the other states of matter, the charged particles in a plasma will react strongly to electric and magnetic fields (i.e. electromagnetic fields). If a plasma loses heat, the ions will re-form into a gas, emitting the energy which had caused them to ionize.
Over 99% of the matter in the visible universe is believed to be plasma.."

Disregard "palsma is very hot. It is not. It is high enrgy due to the electric fields that pass through it. 19th centuury astrophysisists of today use TEMPERATURE in space to describe a high energy gas because someone from the 19th century said there is no electricity in space. Even though WE KNOW negative and positive ions are screaming around our solar system. (Electrical engineers know that if ions move an electric field and a corresponding magnetic field MUST ARISE. Astronomers….not so much.

"Plasma is an electrically neutral medium of unbound positive and negative particles (i.e. the overall charge of a plasma is roughly zero). Although these particles are unbound, they are not "free" in the sense of not experiencing forces. Moving charged particles generate an electric current within a magnetic field, and any movement of a charged plasma particle affects and is affected by the fields created by the other charges. In turn this governs collective behaviour with many degrees of variation.["
These complex movements of positive and negtive ions create Birkland Currents.
"also known as field-aligned currents, magnetic ropes and magnetic cables). "
Plasma physicists suggest that many structures in the universe exhibiting filamentation are due to Birkeland currents. Peratt notes that "Regardless of scale, the motion of charged particles produces a self-magnetic field that can act on other collections of charged particles, internally or externally.[15] Plasmas in relative motion are coupled via currents that they drive though each other". (See Plasma scaling)
"As an example, take an auroral sheet with a thickness of 1 km. A laboratory simulation might have a thickness of 10 cm, a factor of 104 smaller. To satisfy the condition of this similarity transformation, the gaseous density would have to be increased by a factor of 104 from 104 m-3 to 108 m-3 (1010 cm-3 to 1014 cm-3), and the magnetic field would have to be increased by the same factor from 50 microteslas to 500 milliteslas (0.5 gauss to 5 kilogauss). These values are large but within the range of technology. If the experiment captures the essential features of the aurora, the processes will be 104 times faster so that a pulse that takes 100 s in nature would take only 10 ms in the laboratory. "
