If you take preliminary physics, you learned about “basic forces”. This is similar to: All interaction is the result of one or more of the five basic forces: a strong nucleus, a weak nucleus, gravity, electric and magnetic. “Doing physics” means identifying the game forces.
However, there is a problem that may not be mentioned: the forces you see depend on your point of view – “Your reference frame”. Look from the window. Trees, houses, grass – all they are fixed, right? But look from space to the same point and move a thousand miles per hour. You still looked like you were moving with it.
We have the same problem with electric and magnetic fields. Depending on your reference frame, what seems to be a magnetic force from one point is one electrical force from another.
Is your brain still melted? Just wait – it even becomes stunned. To understand what happens here, let’s first look at the electrical and magnetic forces in isolation.
Electric force
You see all the things around you? EverythingAll of this is made of just three things: proton, electron and neutrons. When you think it is a wild. Two of these essential particles have an electric charge: an electron with a negative charge and a positive proton.
If an object has more than protons, it will have a pure negative charge. So, that sock in the dryer that sticks to everything? By rubbing against other clothes, removed extra electrons. If a object loses an electron, it has a positive charge.
We can calculate the electrostatic force between two charging objects with the law of the Colum. This says the force between them depends on the product of their accusations and how far they are. To show, I put this advanced contradiction in the infrastructure, which has two small floor blocks hanging on the strands. I gave them both negative costs, which means they get one another.
