← ScienceWhich risk increases when a high-frequency electromagnetic field is rapidly switched near a conducting surface?
A)Reduced skin effect impedance
B)Increased surface plasma formation✓
C)Decreased electron mobility effects
D)Enhanced quantum tunneling currents
💡 Explanation
Increased surface plasma formation occurs because rapid switching enhances transient field gradients, therefore creating strong potential gradients that exceed the ionization threshold of nearby gas molecules initiating plasma formation, rather than other effects that require specific material properties or conditions.
