Which one of the following functions, like a motor?
Correct answer: A. galvanometer
- A. galvanometer
- B. ammete
- C. voltmeter
- D. all of the above
Explanation
A galvanometer functions like a motor. A galvanometer is an instrument that detects and measures small electric currents. It operates based on the principle of electromagnetic induction, similar to a motor. When a current flows through the coil of a galvanometer, it experiences a torque, causing it to rotate, much like the rotor of a motor.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
