In the film Super 8, an electro-magnetic field wrecks over a small town.
Is there a magnet that big on Earth that can have enough power to turn cars and create drastic disasters like the ones shown in the film?
You answered Yes. That is correct! A magnet that powerful does exist here on earth called the "magnetar" also called the soft gamma repeater. Only ten of these magnets exist here on earth and they are powerful enough to slow down a locomotive from a quarter-million miles away. Meaning that if it can do that at a long distance it is very powerful to tip over cars and possibly destroy or maybe affect a small town. The magnetar has an electromagnetic field of 100 billion Tesla which is the magnetic field strength or magnetic-flux density. It is still nearly impossible that a human being will possibly create something that powerful like a "magnetar".
