Floyd, aluminum is paramagnetic, NOT ferromagnetic. Aluminum is
affected by electromagnetic fields, as is copper. The windings of most
electric motors are made of copper, and the electrons in the copper
atoms interact with electromagnetic fields to make the armature of
an electric motor turn. Some electric motors have been made with
aluminum windings. Calling his aluminum recycling device an "aluminum magnet" may sound suspicious to the uneducated critic,
but I have no doubt whatever that it would work, IN PRINCIPLE. My
more sophisticated question is whether it is energy efficient, or does
it waste most of the electrical energy in heating the cans through
induction? When I was attending a technical school, I did not believe that aluminum was magnetic, either, until the instructor put
an aluminum pot onto a box which contained a rotating electromagnetic field. The pot began to rotate, following the motion of
the field! The instructor warned me not to touch the pot, because the
electromagnetic induction was making it VERY hot. Furthermore,
scientists in the United States and The Netherlands, experimenting
with very powerful magnets, have succeeded in levitating living
animals and insects, which contain only trace amounts of iron in their
bloodstreams. So, disbelieving in the possibilities of science can make
a bigger fool out of you than you already appear to be. A Dutch evangelist offered to buy the powerful magnet used to levitate a tiny
frog. He wanted to use the invention to produce a miracle for his
congregation, levitating himself during a Sunday sermon. He sent
money to the scientists to buy the rights to the invention. |
