It can be defined as the number of magnetic field lines passing through the given closed surface.
Mathematically it can be given by
Where, is the magnetic flux, B is applied magnetic field and A is surface area of closed object and is the angle between magnetic field lines and area vector of surface.
Faraday Law of EMF
Faraday Law of EMF states that the induced emf in a loop equals to the negative of the time rate of change of magnetic flux through the loop.
Mathematically it can be given by
Where, e is the induced EMF.
