The magnetic flux ( \(\Phi\) ) is:
- A Scalar quantity and its SI unit is \(Wb m ^{-2}\)
- B Vector quantity and its SI unit is \(T m ^2\)
- C Scalar quantity and its SI unit is \(Tm ^2\)
- D Vector quantity and its SI unit is \(Wb m ^{-2}\)
Answer & Solution
Correct Answer
(C) Scalar quantity and its SI unit is \(Tm ^2\)
Step-by-step Solution
Detailed explanation
Magnetic flux \((\Phi)\) is the dot product of the magnetic field vector and the area vector \((\Phi=\overrightarrow{ B } \cdot \overrightarrow{ A })\), which makes it a scalar quantity. Its SI unit is the Weber (Wb), which is equivalent to Tesla \(\times\) meter…
