Which expression gives magnetic flux?
- qVB sin\(\theta\)
- \(\frac{\mu \phi I}{2 \pi r}\)
-
BA cos \(\theta\)
- -N \(\frac{d \phi}{dt}\)
The correct answer is: 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).
