What happens to the Hall voltage when the magnetic field strength increases in a current-carrying conductor?.
- A.The Hall voltage decreases.
- B.The Hall voltage increases.
- C.The Hall voltage remains constant.
- D.The Hall voltage fluctuates.
Model answer
What a good answer should say
- The Hall voltage increases.
Explanation
Why this works
The cause is the increase in magnetic field strength. The mechanism involves the Lorentz force acting on the charge carriers in the conductor, which results in a greater separation of charges.
The effect is an increase in Hall voltage, leading to a more significant voltage output that can be measured, enhancing the sensitivity of magnetic field detection.
