From this rotation, we can calculate the difference in orthogonal velocity components, find the anisotropic permittivity, find the gyration vector, and calculate the applied magnetic field \ mathbf { H }.
2.
Where \ varepsilon'is a real symmetric matrix and \ mathbf { g } = ( g _ x, g _ y, g _ z ) is a real pseudovector called the "'gyration vector "', whose magnitude is generally small compared to the eigenvalues of \ varepsilon '.
