← ScienceWhich effect occurs when a pulsed electromagnetic field induces high-frequency oscillations in a dielectric capacitive sensor?
A)Dielectric heating due to hysteresis losses✓
B)Electromagnetic interference couples into adjacent circuits
C)Mechanical resonance within the sensor housing
D)Capacitance saturation limiting voltage resolution
💡 Explanation
If a pulsed electromagnetic field interacts with a dielectric material, dielectric heating can occur because repetitive polarization reversals induce energy dissipation via hysteresis. Therefore dielectric heating results, rather than interference, resonance or saturation because it is the dominant loss mechanism in this specific scenario, unlike the other options.
