← ScienceWhich outcome during lightning strike events results from electromagnetic induction?
A)Surge current induced in powerlines✓
B)Ionization in the surrounding atmosphere
C)Formation of stepped leader channels
D)Triboelectric charging in storm clouds
💡 Explanation
Surge current occurs because the rapidly changing magnetic field from the lightning induces a current in nearby conductors through electromagnetic induction; therefore, surge current is observed, rather than ionization or initial conditions of lighting formation under static electricity.
