Exam-style question
Try this first
In a Hall effect sensor, what is the primary function of the sensor?.
- A.To measure the temperature of the conductor.
- B.To detect the presence of a magnetic field.
- C.To increase the current in the circuit.
- D.To convert electrical energy into thermal energy.
Model answer
What a good answer should say
- To detect the presence of a magnetic field.
Explanation
Why this works
The primary function of a Hall effect sensor is to detect magnetic fields. It does this by measuring the Hall voltage generated when a magnetic field interacts with the current flowing through the sensor.
