  • A QVB sin\(\theta\)
  • B \(\frac{\mu \phi I}{2 \pi r}\)
  • C BA cos \(\theta\)
  • D -N \(\frac{d \phi}{dt}\)
Correct Answer: Option C
Explanation:
the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface.
It is usually denoted Φ or ΦB. The SI unit of magnetic flux is the weber
Mathematically it is represented as B = Φ/A
where B is magnetic flux density in teslas (T),
Φ is magnetic flux in webers (Wb), and
A is area in square meters (m2).
There is an explanation video available below.
