Why will there be no induced current?

    Why will there not be an induced current in a field parallel to a current carrying wire?

    Will you please post the reference, textbook, paper, or whatever that is the source of your question?

    Current cannot be induced in a field. Current needs some conductor like copper or ionized gas in order to flow.

    those pics are not referring to current induced into a field

    and as bobby said ... it cannot be, so what really is your question ?

    If no field lines cross (i.e., cut through) the enclosed area, there is no changing field. If there is no changing field, no voltage is being induced.
