.That was pretty weak.
Hang a 100 ton block of rock. Hang a one pound bar of steel perfectly parallel adjacent to it so it just rests against the surface. Approach, you don't even have to contact it, the one pound bar with a refrigerator magnet. It will pull the bar away from the block. The magnetism in that refrigerator will overcome the gravity pull of the block, PLUS the pull of gravity of the earth on the bar, as for it to swing away it has to rise up a bit. The arc of the string.
Iron filings in a flux field line up between the poles. Each filing is a separate magnet. You will get the same effect if you magnetize one filing, the rest will get caught in the filed and start adding up until the total excess of magnetism is used up.
The iron is EM neutral until an external magnetic field affects it, and it tries to pass that excess on.
Over 99% of the matter in the universe is not EM neutral.
I posted a link a few days ago about short bursts of inrafred light being used to change magnetic domains. This was mainstream science research. This was light, EM, introducing an excess of magnetism to an EM neutral material. How far does light travel in this universe? As far as you can see?
Light particles can travel at least 13 billion light years and alter the EM signature of a neutral material, then making it subject to other magnetic fields more local to it. Energy 13 billion years from the past.
Oh my god. I apologize Dave. I'll stop making fun of you.
It really isn't your fault. And I'm a total ass for being mean to you.
