Hi all,
If this is off topic please point me in the correct general direction.
As an electrical engineer I was taught that if I move a magnet close to a
wire connected to a volt meter (VM), I would get a reading because of
Faraday's law of induction. How does this work at the particle level ?
Magnetic fields are generated by the spin of electrons in the permanent
magnet material, right ?. How does this magnetic field makes the electrons
in the atoms of the wire "flow" ? The part that makes me think the most is:
Why do I have to move the magnet ? Aren't the particles (electrons, protons,
quark,etc) already moving waaaay faster than me moving the magnet ? Why
would me moving the magnet make any difference compared to the speed of the
particles ?
Thanks |

Còlòns don't go after runons. Don't space punctuation.
makes -> make/makan
Charges whorl and trend; spin is a misnomer fro dumb scientists. Their
motions don't "generate" magnetism; they /are/ magnetism. Read my
criticism of physicists in my thread about Element 115. The elèctròn
is one fitt of a spring that switches between still (elèctric) and
swiff (magnetic). That's all there is to it.
