← ScienceWhich consequence results when a high-voltage power line oscillates near a farmhouse?
A)Increased transformer core saturation occurs
B)Localized ground subsidence increases greatly
C)Radiated electromagnetic induction increases✓
D)Capacitive power system efficiency weakens
💡 Explanation
The oscillating power line creates a time-varying magnetic field; therefore, radiated electromagnetic induction increases, because Faraday's law dictates that a changing magnetic field induces a current flow in nearby conductors, rather than other grounding or load effects.
