Q1. A researcher uses a Hall effect sensor to measure the magnetic field strength in a specific region. What is the principle behind the functioning of the Hall effect sensor?
Answer: Magnetic fields causing a change in voltage
Explanation: Magnetic fields cause a change in voltage, which is detected and used to measure magnetic field strength, whereas the other options describe different principles used in different sensors or measurement techniques.
