← ScienceWhich effect occurs when a strong external magnetic field is applied perpendicular to a Hall effect sensor?
A)Increased sensor output voltage✓
B)Reduced sensor power consumption
C)Reversed polarity of output signal
D)Lowered sensor operating temperature
💡 Explanation
When a strong magnetic field is applied, the Lorentz force on moving charges within the sensor increases significantly, leading to a greater charge separation and a larger potential difference across the sensor. Therefore output voltage increases, rather than reduced consumption, reversed polarity or lowered temperature which require alternative mechanisms.
