Note: Electromagnetic field As summarized in previous chapters, electromagnetic field is mathematical abstraction of two projections and , which meets Maxwell equations and may be represented by field lines defined as Definition: Open field line Field line is open, when it is not closed in plasma. Definition: Closed field line Field line is closed, when it is closed in plasma. Theorem: Magnetic field line equation Lets assume electromagnetic field with field lines. Then Proof: The theorem results from field line definition directly which is a vector equation of three scalar equations and thus may be written
