What is Magnetic Flux?
Flux is basically count of number of lines crossing a surface.
Consider a closed curve enclosing an area A (as shown in the figure). Let there be a uniform magnetic field B in that region. The magnetic flux through the area A is given by
In case of a coil of area A having N turns
Magnetic flux is a scalar quantity. It can be positive, negative or zero.
The dimensional formula of magnetic flux is [ML2T–2A–1].
The SI unit of magnetic flux is weber. The CGS unit of magnetic flux is maxwell.

Direction of Area Vector
- Area vector is ⊥ to the surface.
- For open surface choose one direction as the area vector direction and stick to it for the whole problem.
- For closed surfaces outward normal is taken as area vector direction
