In the movie Sleight, the second from the new independent studio BH Tilt, a young street magician (Jacob Latimore) is left to care for his little sister after their parents passing and turns to illegal activities to keep a roof over their heads.
When he gets in too deep, his sister is kidnapped and he is forced to use his magic and brilliant mind to save her.
The plot climax relies on the power of an electron magnet. The power pack and the wires are all to create a more powerful magnet. Magnets work on substances with iron in them. They have no effect on plastics or nearly all other metals, such as lead or aluminum. Bullets usually lead or brass, and certainly the bullets used in the gun at the end, would not have been affected by any magnet.
