Subject: does hitting a magnet weaken its magnetic strength ... I am doing a science fair project on "does hitting a magnet weaken its magnetic strength" and I know that it does, but I need more scientific information about magnets and why this occurs. My teacher said to look up some information on ions.

And the reason is this: In a magnet the electrons in the atoms are spinning in the same direction, which gives a magnet its magnetic domain—north or south—and creates a magnetic field. If the electrons are spinning every which way, the domains are scattered and the magnet is not magnetized.

Other possibilities: the field could stop weakening and begin to strengthen, or it could weaken to the point that it suddenly flips polarity—that is, ... Ancient lava flows from the Hawaiian Islands reveal both the strength of the field when the lava cooled and its orientation—the direction of magnetic north and south.

PETER OLSON: Today something very strange is going on with the Earth's magnetic field: its strength is rapidly decreasing, so fast that at the current rate ... And you can see that if I perturb this magnet just slightly, how fast it recovers the original position gives us indication of the strength of the magnetic field.

Sergei Dudarev, of the UK Atomic Energy Agency, found that steel loses its strength above 500C because its molecules undergo a physical transition from one state to another due to magnetic fluctuations. "The steel didn't melt, it just became soft.
