Line 42:

: <math>\lambda_D = \left(\frac{kT_e}{4\pi ne^2}\right)^\frac{1}{2} = \frac{v_{Te}}{\omega_{pe}} \approx 7.43 \times 10^2\,\left(\frac{T_e}{n}\right)^\frac{1}{2}\ \mbox{cm}</math>

| '''ion inertial length''', the scale at which ions decouple from electrons and the magnetic field becomes frozen into the electron fluid rather than the bulk plasma:

: <math>d_i = \frac{v_{a}}{\omega_{ci}} = \frac{c}{\omega_{pi}} \approx 2.28 \times 10^7\,\frac{1}{Z}\left(\frac{\mu}{n_i}\right)^\frac{1}{2}\ \mbox{cm}</math>

| '''[[mean free path]]''', the average distance between two subsequent collisions of the electron (ion) with plasma components:

: <math>\lambda_{e,i} = \frac{\overline{v_{e,i}}}{\nu_{e,i}}</math>,
