Good advice above, apart from the bit that says "The magnet test: A true meteorite will show a reasonably strong attraction to a magnet".
This is not true.
A meteorite which has visibly metallic portions will always show a strong attraction to a magnet because the metal can only be principally iron, with some nickel. Some meteorites may contain significant metal which is not readily visible and those will be moderately attracted to a magnet. Not all meteorites are of these types, though. Some contain only low amounts of metal and will show only a weak attraction to a magnet. Some contain no metal at all and will show no attraction.
