The S.I. unit of magnetic flux is:
Correct answer: C. Weber
- A. Tesla
- B. Joule
- C. Weber
- D. Newton
Explanation
The correct answer is Weber, which is defined as the amount of magnetic flux that passes through a surface area of one square meter in a magnetic field of one tesla. The formula ΦB = BA = Tm² = weber illustrates how magnetic flux (ΦB) is calculated as the product of magnetic flux density (B) and area (A).In contrast, a tesla measures the strength of the magnetic field itself, while joules measure energy, and newtons measure force. Therefore, all of these options except weber are incorrect as they represent different physical quantities unrelated to magnetic flux.

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.
