This is the mental ability to manipulate and control the magnetic metals with one’s mind. Cobalt, Nickel, and Iron. So you could move steel swords, but not bullets - unless they contain iron, cobalt, or nickel. Some armor-piercing ones do contain steel, so it's up to GM discretion. The psychic Willpower + Magnetic Manipulation.
Like Psychokinesis, you can make a parry style maneuver by rolling a Willpower/MM roll to defend. If you win, you've stopped the metallic object and take no damage.
Tossing an object at someone requires a Willpower/MM roll. The damage from such an attack is the roll's Success Levels x 5, and is modified by the type of damage - a metal baseball bat would do bash, and so would a pipe, but a dagger would be slash, and so would a spork.
Examples: Magneto, Polaris
Cost: 2/level
