Comment Re:Why Magnets attracts (Score 1) 656

The electromagnetic force holds everything together. It's the main force that explains why things are as they are. Why you are solid, why you can't walk through walls, etc.

With a magnet, the electrons in the iron (or other magnetic material) are aligned. They all rotating around their atoms in sync. So they attract other materials that can alter their electron's orbits easily, like more iron.

When a lot of atoms are all magnetically aligned like that, the force adds up. When the atoms are all higgledypiggledy, there's no magnetic force.

(Not exactly correct from a scientific standpoint, mainly because electrons don't orbit, they're a probability function, but it's ok for kids if you draw a few diagrams)

Sound recordings in the 1950s were adequate quality so invest in some vintage vinyl.

Rip it, run it through a scratch and pop removal program, mp3 it and play that to the horses.

50 years, then copyright expires, so she can go and get any old record published before 1959 and play that without hindrance.

They take her to court, she screws them for libel. :)
