…it was important for different kinds of quantities to have different names, even though the units are the same. So they called it Oersted. So if you want to, You can call it Oersteds if it's H. So you can remember which one they're talking about, but…

…in ampere turns per meter do you have to worry about it. Then it's the other H. But if it's in Oersteds or Gauss, remember the Oersted is the Gauss and the 10 to the fourth is an MKS. And you got my age then, OK? It's a horrible business unit. Now…

…of physics, because there was light and there was electricity and magnetism. They were unified experimentally through Faraday and Oersted. electricity and magnetism. But all of a sudden, light was no longer something else. It was only electricity and…
