- pyrfu.pyrf.plasma_beta.plasma_beta(b_xyz, p_xyz)[source]#
Computes plasma beta at magnetic field sampling
\[eta =\]rac{P_{th}}{P_b}
where : \(P_b = B^2 / 2 \mu_0\)
- Parameters:
- b_xyzxarray.DataArray
Time series of the magnetic field.
- p_xyzxarray.DataArray
Time series of the pressure tensor.
- Returns:
- betaxarray.DataArray
Time series of the plasma beta at magnetic field sampling.
