The question is: What is the device which is used to measure magnetic field
Correct answer: A. Magnetometer
- A. Magnetometer
- B. Voltmeter
- C. Wilson-cloud chamber
- D. None of the above
Explanation
A magnetometer is a device that measures the strength and direction of a magnetic field. It is used in a variety of applications, including navigation, geology, and physics research.A voltmeter is a device that measures the voltage difference between two points.A Wilson-cloud chamber is a device that is used to detect and track charged particles.

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.
