Is It Electric or Magnetic? Depends on Where You Stand

If you take preliminary physics, you have learned about the “basic powers”. Something like this: All reactions are the result of one or more than five basic powers: strong nuclear, nuclear, attractive, electric, and magnetic. “Doing physics”, then, means determining the forces in playing.

There is a problem, though, maybe not mentioned: the powers you notice depend on your point of view – the “reference frame”. Search from the window. Trees, homes, promoters – they are all fixed, right? But look at the same place of space moving a thousand miles per hour. It seemed still for you before because you were moving with it.

We have the same problem with electric and magnetic fields. Depending on your reference stretching, what appears to be a magnetic power of one spot is an electric power from another.

Is your mind melting yet? Just wait – even the strangest. To understand what is going on here, let’s first look at the electrical and magnetic forces in isolation.

Power

You see all these things around you? Everything. Everything is made of only three things: protons, electrons and neutrons. This is a type of wild when you think about it. Two of these basic molecules have an electric charge: negatively charged electron and positive protection.

If the object has more electrons than protons, it will have a negative and clear charge. So, this is a sock in the dryer that connects everything? Additional electrons were picked up by rubbing against other clothes. If you lose an electrons, it will have a positive charge.

We can calculate the electrostatic power between two lymphs charged with Colom law. This says that the force between them depends on the outcome of their fees and their separation. To clarify, I built this high -tech Contraption below, which contains two small blocks of foam hanging on the strings. Both gave them a negative charge, which means that they will hit each other. check it out:
