← ScienceWhen a solenoid valve's coil overheats, which consequence results from increased resistance?
A)Reduced magnetic field strength✓
B)Increased flux linkage saturation
C)Enhanced valve response time
D)Amplified back EMF generation
💡 Explanation
The magnetic field weakening is due to Ohm's law; increased temperature raises resistance, lowering current for the energizing process. Therefore, electromagnetic force reduces, rather than causing saturation because fewer charge carriers contribute.
