    in flyback converter where the energy stored in core or in air gab or in winding
    thanks

    I believe it's actually stored in the core, although if the core is gapped there may be some stored in the flux across the air gap.

    Isn't the energy in the magnetic field, which in most cases passes through the core (solenoid), or is entirely contained within the core (toroid).

    In a word or seven; Yes the energy is stored in the magnetic field, the core has the effect of concentrating the lines of magnetic flux.

    The OP's question regarding the flyback converter was clearly about energy storage in the transformer. So I guess their question has been answered.

    One might extend the notion to any physical situation in which an electric current exists - there will be energy "stored" in the magnetic field created by the current.

    If you have ever had a shock off an auto ignition coil you get a very clear sense of that energy.

    One however should not forget that there is a second energy storage component in the flyback converter - namely the capacitor.

    Which stores the energy in the electric field, of course. ;)
