Magneto

Magneto is a passive item.

Effects

 * Pickups (e.g. hearts, coins, keys, bombs, etc.) are attracted to Isaac.
 * The attraction enables the item to pass/fly over pits or rocks, but not through Key Blocks.
 * Hearts are only attracted if Isaac could pick them up with his existing heart containers.
 * Batteries act in a similar manner to hearts in that they will only be attracted towards Isaac if his active item isn't fully charged.
 * A few enemies (like the Horf) are drawn toward Isaac as well.

Trivia

 * The item's name may be a reference to the X-Men villain, Magneto.
 * This item's coloration and placement on Isaac's head may be in reference to Magnet Man, a villain from the early Mega Man games.
 * Despite what the description says, Magneto will not attract passive or active items.
