o you thought your fridge magnet was pretty neat. You obviously haven't met the most powerful magnet
known to man. Their density and rapid rotation (several times per second) enormously increases the
power of their magnetism. If you placed a magnetar where the Moon is, 400,000 kilometres away, it
could still wipe your credit cards and rip spoons out of your pockets. A magnetar is a type of
neutron star with an incredibly strong magnetic field (a million billion times stronger than that of
the Earth), which is formed when certain stars undergo supernova explosions.
