What is fringing of electric and magnetic fields? What is the physics behind it?

    I want to know what exactly is magnetic and electric field fringing and what is the cause of it?

    you have a fringing field around the edge of a parallel plate capacitor
    because the plates are not infinite. If the plates were infinite the E field lines would go straight across to the other plate.
    from far away it kind of looks like an electric dipole.
