Do SuperMagnets (powerful Neodymium magnets) have enough power to offset a bullet's trajectory?

I'm getting into a duel in the next couple weeks: pistols at 15 paces. We'll be out in the open fields. So I had this idea. What if I just brought a blowdart with me instead along with a superconducting magnet to attract his bullet? That way, his weapon would be useless, and my poisoned dart would reign victorious. Of course, this all depends on whether or not the bullet would actually be affected by the magnet. Does anyone have this sort of knowledge?
