Meteorites fall into two classes, stony and iron. There is a belt of meteoric material near Mars, from which many of our meteorites come. Perhaps the debris from a broken planet? The iron meteorites, in fact iron-nickel mixtures, are magnetic. the stony meteorites are not. Have a look for Bode's Law in a reference source.
