In a Hall effect sensor, what happens to the Hall voltage when the magnetic field strength is increased?.
- A.The Hall voltage decreases
- B.The Hall voltage remains unchanged
- C.The Hall voltage increases
- D.The Hall voltage fluctuates
Model answer
What a good answer should say
- The Hall voltage increases
Explanation
Why this works
The cause is an increase in the magnetic field strength applied to the Hall effect sensor. The mechanism involves the Lorentz force acting more strongly on the charge carriers in the conductor as the magnetic field increases.
The effect is that the Hall voltage generated across the sensor becomes larger. The consequence is that this allows for more precise measurements of the magnetic field strength, enhancing the sensor's functionality.
