Why is the electric field ,in a wire carrying a current ,at right angle to magnetic field?

Answer 1

That's just the way it is, a changing electric field creates a changing magnetic field perpendicular to it.

Answer 2

Normally, I think it would be, why does a magnetic field form at a right angle to current flow?

It has to do with the construction of the electrons themselves. An electron has tilt, speed, magnetic field, electric, and mass properties. What we are interested in are the magnetic field, electric equator, and mass.

The electron is formed when a high energy photon overlaps part of its frequency by completing an arc of more than 360 degrees. When this happens frequency is bonded to frequency and and electron remains as a mass.

There are magnetic lines that form in one-half of the electron, then there is an electric equator that divides the magnetic lines from the other half of the electron - which is the mass (offers Resistance to movement). The mass has an equal amount of energy as the extended magnetic lines.

When a current flows along a wire the magnetic lines extend outward toward a location of least resistance. The same polarity magnetic lines repel each other toward the interior of the wire. The greater the voltage (pressure) inside the wire, the greater the extending magnetic lines, due to resistance to voltage. The electric fields do not repel one another as do extending magnetic lines and they are able to line up in direction of travel.

Answer 3

that's devoid of problem a universal statement of nature that the stress a magnetic field exerts on a moving cost is perpendicular to each and each the concern and the stream. notwithstanding to complicated slightly more beneficial on the mathematical interpretation of this... What this suggests is that the speed of the shifting cost will in no way change. In different words, no kinetic skill is extra to a moving electric powered cost through a magnetic field, only an electric powered field can attempt this. So, the rationalization that it well-knownshows this habit is once you evaluate that the magnetic section can't do any paintings on an electric powered cost.

Answer 4

I have another question: why do electric fields even exist? Magnetic fields? We really don't know why. We have many laws to describe the phenomenon (Maxwell's Equations), but as to why, there is some debate. That is what the "Theory of Everything" is concerned with, as well as physics in general.

Answer 5

well, I think its at a right angle since the electric field is all around the wire. Maybe picture a candle. The wick is the wire, the wax is the field. so its from the wick outward in one plane, all directions, a right angle. Not sure about the mag field.

Answer 6

I comes from the solution to Maxwell's equation relating current to magnetic field. For steady state condition (nothing varies with time) the equation is

DEL cross H = J

H = magnetic field intensity (vector)
J = current density (vector)

DEL is a vector differentiation operator (partial derivates with respect to three directions) and cross is the vector cross product. The vector cross product results in a vector at right angles to J.
