    Hi Jhenrique! :smile:

    The interior product is pretty much the same as in ordinary geometry …

    it gives the component (of, say, a force) in a particular direction.​

    The exterior product is useful for combining eg two forces or a force and a position …

    eg the exterior product of the 2-form (E;B) electromagnetic force with the 1-form r position is the 3-form (E;B) ##\wedge## r whose dual is the 1-form force. :wink:
