    What is the context of the question?

    And you normally need a transformer for flyback operation...

    A boost inductor is a two terminal inductor.

    A flyback inductor is a four terminal device. It consists of a two terminal inductor with an ideal transformer connected across it.

    You magnetize it just like a boost inductor. But when the inductor demagnetizes, it does it through the transformer allowing you to provide isolation and transformation.
