Abstract: Discusses the magnetic coupling effects on a communication line from a crossing power line, and gives two ways to calculate the mutual inductance between crossing lines. Numerical computation and comparison are made. The corresponding formulae for calculating induced voltage and induced current are derived.

Key words: electromagnetic field, power line, communication line, crossing, magnetic coupling
