How does the Hall voltage depend on the strength of the magnetic field?.
- A.It is directly proportional to the magnetic field strength.
- B.It is inversely proportional to the magnetic field strength.
- C.It remains constant regardless of the magnetic field strength.
- D.It depends on the temperature of the conductor.
Model answer
What a good answer should say
- It is directly proportional to the magnetic field strength.
Explanation
Why this works
The Hall voltage increases with an increase in the magnetic field strength, as the force acting on the charge carriers becomes stronger, leading to a greater separation of charges and thus a higher voltage.
