← ScienceWhich risk increases when a Faraday cage shield's openings exceed skin depth at the excitation frequency?
A)Magnetic field leakage occurs✓
B)Capacitance reaches parasitic levels
C)Eddy current heating diminishes
D)Dielectric breakdown is accelerated
💡 Explanation
Magnetic field leakage increases because the skin currents redistribute around larger openings, diminishing **Faraday shielding**. Therefore, the cage is less effective at blocking EM radiation, rather than altering capacitance or heating because magnetic fields escape.
