Which expression gives magnetic flux?
A
qVB sin\(\theta\)
B
\(\frac{\mu \phi I}{2 \pi r}\)
C
BA cos \(\theta\)
D
-N \(\frac{d \phi}{dt}\)
Verified Correct Answer: C.
Physical Principles & Numerical Solution
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).
