Electromagnetism to deviate the path of an incoming bullet

  1. Mar 7, 2005 #1
    I was thinking if electromagnetism could be used to deviate the path of an incoming bullet?

    U see,electromagnetism requires that bodies must have nonzero electrical charge.(in the first approximation).Now,the bullet may not be neutral.The friction with the pipe (?) in the pistol could deprive him of electrons,but i wouldn't count on a massive deviation by em.fields...

    Sure. Take a very thick plate of hard steel. Place it at a 45 degree angle to the bullet path. When the bullet gets close enough to the steel plate, the electomagnetic fields of the electrons and protons in the atoms in the bullet will interact with the electomagnetic fields of the electrons and protons in the atoms in the plate and the bullet (what is left of it) will deflect.

    Use a lot of UV-EM for a photoelectric effect that would eject electrons until it is sufficiently charged to be deflected by a DC field or magnetism (though ) ...


    Radiate so much IR (absorbed by metals) that the bullet melts and scattered before it hits target...


    Radiate with so much visible (reflected) that radiation pressure alone deviates it...


    Radiate so much gamma and x-rays that... well, much of the above + nuclear reactions that might be preferentially oriented to add to radiation presure...

    When a bullet hits it's target, the electrons in the bullet are repelled by the electrons in the target, via Coulomb interaction. The result being that the bullet bounces off, thereby being deviated from it's trajectory by Electromagnetism.

    Although that's not the real answer you were looking for, right?

    This sounds like my brother's idea of deflecting raindrops from a windshield using magnetic fields. It's like using a supercomputer to calculate your gas bill.

    So it has already been done? Damn. *throws away prototype*
