Which expression gives magnetic flux?

A.

qVB sin\(\theta\)

B.

\(\frac{\mu \phi I}{2 \pi r}\)

C.

BA cos \(\theta\)

D.

-N \(\frac{d \phi}{dt}\)

Correct answer is C

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).
