A) tesla
B) oersted
C) weber
D) Gauss
Correct Answer: C
Solution :
The magnetic flux is defined in the same way as the electric flux in Gausss law. For a uniform magnetic field B crossing the plane of area A at an angle \[\theta \] with the normal to the plane \[\phi =BA\cos \theta \] \[\therefore \] Unit of magnetic flux = unit of magnetic field \[\times \] unit of area \[=\frac{Wb}{{{m}^{2}}}\times {{m}^{2}}=Wb\] Hence, SI unit of magnetic flux is weber.
