When two systems are not in phase, which is usually the case for different frequencies, then there exists a certain phase shifting between them. With the value $α_f$, the shift of phase to ° can be set each system separately. The phase-shift is relevant for calculation of the magnetic field.

$\alpha_{\mathrm{f}}$

°

Id | Frequency |
---|---|

0.0 | 0° |

60.0 | 60° |

120.0 | 120° |

180.0 | 180° |

240.0 | -120° |

300.0 | -60° |
