    I got a motor coil on the shaft still with contact plates and gear intact, and I was wondering if it could be used to generate an EMP or be used as an induction coil.

    An EMP requires the detonation of a nuclear weapon, or a lightning strike. As such it would be contrary to the TOS and general sanity.

    I have done my research my friend. EMPs can be generated with a quick and sudden high voltage to a induction coil or and coil really

    the question should be. Do motor coils count as induction coils? The part the recieves the electricity and does the majority of the work

    should be quite educational for your topic..

    Induction usually means a voltage is induced in a coil by magnetic effect.
    The 'shorted' turns on a induction motor rotor is an example, and that is only one turn.

    Voltage really doesn't matter to an inductor, current is the thing.

    The American military has been developing an EMP gun which combines a heavy coil with a shaped charge explosive.

    I only glossed over the article, but I gather its basically a funnel shaped spiral conductor encased in explosive - when its detonated, the inductor collapses to much smaller dimensions, that produces an abrupt risetime in the current through it which comes pretty close to EMP.
