Since the EM wave travels at the fastest speed could we say the fastest cause and effect interaction could be the change in electric field generating the magnetic field ?
Look at Maxwell’s equations, they do not say that the electric field gets disturbed first.Jaysal said:How could it be the other way around its it the electric field that gets disturbed first.
Yes. Two events where the second is on or inside the future light cone of the first can be causally related, and the time order is fixed. That is, there is an unambiguous "first event" and "second event", and all observers will agree which is which. Events that are outside each others' light cones cannot be causally related and their ordering is frame-dependent. But it doesn't matter, as you say.FactChecker said:Is it correct to say that the speed of light gives the limit that a cause-effect relationship can exist and that this is the reason that, although there can be disagreement about simultaneity, the simultaneity disagreement will never be great enough to cause a disagreement regarding cause-effect?
The main difference between electric and magnetic fields is the type of force they exert on charged particles. Electric fields exert a force on charged particles, causing them to move in a certain direction, while magnetic fields exert a force on moving charged particles, causing them to change direction.
Electric and magnetic fields are interconnected and can influence each other. When an electric current flows through a wire, it creates a magnetic field around the wire. Similarly, a changing magnetic field can induce an electric current in a nearby wire.
In an electric and magnetic field, the fastest cause and effect is the propagation of electromagnetic waves. These waves travel at the speed of light, which is approximately 3 x 10^8 meters per second.
Electric and magnetic fields can affect matter in various ways. They can cause charged particles to move, which can lead to the production of electric currents. They can also exert forces on matter, such as the force that keeps electrons in orbit around the nucleus of an atom.
Electric and magnetic fields can be measured using specialized instruments such as voltmeters and magnetometers. These instruments measure the strength and direction of the fields and can provide valuable information about their effects on matter.
