← ScienceWhich risk increases when a pulsed electromagnetic field is applied to a dense plasma?
A)Increased Langmuir wave damping
B)Enhanced magnetic field penetration✓
C)Reduced parametric decay instability
D)Lowered collisional absorption rates
💡 Explanation
Enhanced magnetic field penetration occurs because the skin effect can weaken due to induced currents that locally modify the plasma conductivity. Therefore, magnetic field penetration increases, rather than being impeded by classical resistive diffusion because collision rates change.
