Is it electrical or magnetic? Depends on where you are

If you take introductory physical, you have learned about the “fundamental forces.” Goes to something like this: all interactions of one or more than five basic forces: strong nuclear, electric, electric, and magnet. “Making physical”, then it means identifying forces in play.

There’s a problem, however, that could have been mentioned: the forces that observe about your point-your point-your “reference frame.” Look out of the window. Trees, houses, 3 Dipesties – all stationary, right? But look the same place from space and move a thousand miles an hour. You always looked first because it moved with it.

We have this same problem with electrical and magnetic fields. According to your reference frame, that seems to be a magnetic force from a place seems to be an electric force from another.

Your brain still hurts? Just expect – it comes even more foreigner. To understand what is going there, let’s get electric and magnetic forces in isolation.

The electric force

See all those things around you? Everything. I am It’s all made of three things: Protons, electrons, and neutrons. It’s kind of wild when you think. Two of these fundamental particles have an electrical load: Negatively charged electronics and the positive protrudes.

If an object has more electron than protons, you will have a net negative charge. So what hot in the dryer clings at all? Took extra electron burning against other clothes. If an object is losing electrons has a positive charge.

We can calculate the electrostatic force between two charges charges with the law of coulomb. This says the strength between them depends on the product of their charges and how often they are. To illustrate, I built this high-tech compliment below, which has two small blocks of rifle by applying in strings. I gave you both a negative charge, which means they will report. Check it out:
