The Hall effect sensor uses the principle of... to sense the presence of a magnetic object.

Explanation:
Transduction is what’s at work here—the Hall effect sensor converts magnetic field energy into an electrical signal. When current flows through the semiconductor, a magnetic field exerts a sideways force on the charge carriers, creating a voltage (the Hall voltage) proportional to the field. This is a direct energy conversion: magnetic information becomes an electrical signal. Induction would involve generating voltage from changing magnetic flux (Faraday-like), which isn’t how a Hall sensor primarily senses steady magnetic fields, and reflection or refraction are optical effects, not electrical sensing.
