Plasmabeta
The plasma beta ( ) is the ratio of thermal to magnetic pressure in a plasma .
It is thus defined as
- .
- Particle density
- Boltzmann's constant
- absolute temperature
- magnetic flux density
- magnetic field constant
The value is used to describe the behavior of cosmic plasma with a magnetic field, such as B. the solar wind or to describe the plasma in a nuclear fusion reactor . In order for a plasma to be confined by a magnetic field , must apply.
