Granite is not typically magnetic because it usually does not contain large amounts of metals in its chemical makeup. Some specimens of granite have been found to be magnetic based on anecdotal evidence–these specimens have usually hailed from India and exhibited an attraction to rare earth magnets, magnetically speaking.
