Understanding Magnetism - The Physics of Bruce Harvey
... Alnico magnets are not perfectly hard for they will loose some of their magnetism over time and particularly if mistreated. Magnets usually come with a "keeper" made of a soft magnetic material which is used to bridge the gap between the poles. They retain their magnetism longer if the keeper is kep ...

... Ferromagnetism is the name of a curious behavior of iron, nickel, cobalt, and other metals. Tiny regions (mm size) inside chunks of iron can align their magnetic domains, like lining up tiny magnets, to make one big magnetic field. Normally, these domains are not aligned, so when you add up all the ...
