← ScienceWhich outcome occurs to a bridge's damping when exposed to high-intensity electromagnetic fields?
A)Increased hysteresis losses reduce oscillations✓
B)Eddy currents induce supplemental torque
C)Material resonance amplifies vibrational modes
D)Capacitive bypass shorts control circuits
💡 Explanation
The EM field creates eddy currents, which excite resonant frequency oscillations in the steel structure; these undergo Landau damping, because increased hysteresis within the material dissipates energy through heat thereby reducing damping capabilities, rather than increasing torque or bypass.
