Greetings, and thanks for stopping by to check out ATP!
Today we’re going to get small and talk about some of the freaky stuff that happens between current and magnetism. Specifically, we’re going to explore what Hall Effect is and by extension the Lorentz force. If you’re an engineer, you’ll know that the Lorentz force is a perennial favorite topic. And if you’re not an engineer (yet), this is one of those things you just gotta know.
Here come some links!
Hall Effect – https://en.wikipedia.org/wiki/Hall_effect
Because that’s out topic.
Lorentz Force – https://en.wikipedia.org/wiki/Lorentz_force
This is what’s really going on.

Direct from the mouth of the guy that did the work.

How would _you_ quantify current in the mid-1800’s?

In the dark days before SI units.

Because it’s just too cool.
