Drip, drip, drip---the incremental improvement of products and processes 
goes on relentlessly. Plastic magnets won't replace metal ones in common 
use, but will do so in many variants.

*World's first plastic magnet passes "test"*

Posted Sept. 1, 2004
World Science Staff

*The world's first plastic magnet to work at room temperature has passed 
the elementary test of magnetism, the New Scientist 
<http://www.newscientist.com> magazine reported. The magnet’s creators 
at the University of Durham, UK, have used it to pick up iron filings 
from a laboratory bench, according to the publication. *

*In 2001, chemists from the University of Nebraska-Lincoln claimed to 
have created the world's first plastic magnet, but it only worked below 
the extremely low temperature of 10 degrees kelvin. Other researchers 
have made plastic magnets, but typically they only function at extremely 
low temperatures, the publication reported, or their magnetism at room 
temperature is too weak to be of commercial use. *

*So the Durham team can claim to have made the first plastic magnet that 
could be used in everyday products, acording to the magazine. One of the 
most likely applications is in the magnetic coating of computer hard 
discs, which could lead to a new generation of high-capacity discs. *

*Jerry Torrance, a materials scientist based in California who is a 
consultant to some of the world's largest electronics and engineering 
companies, including IBM, told the magazine the work is "a significant 
scientific breakthrough” but that practical applications are probably 
still a long way off.* * *
