Whether the voltage is actually a magnetic force?

AI Thread Summary
Voltage is not a magnetic force; it is an electrostatic force that drives charge carriers through a circuit. The relationship between electric and magnetic forces is defined by electromagnetic principles, where a changing magnetic field induces an electric field, as described by Faraday's law. Voltage represents energy per unit charge rather than a force itself. The discussion emphasizes the importance of established terminology and concepts in electromagnetism, particularly Maxwell's equations, to avoid misunderstandings. Overall, voltage and magnetic forces are distinct, with voltage being a result of electric fields rather than a direct force.

My question is whether voltage is actually a magnetic force that pushes electrons through the electrical circuit. My question arises from the fact that conductor passes through the magnetic field and if the circuit is closed we have the electron movement as some force pushes the electrons it should be a magnetic force and I think we called this force as voltage of course this is just a theory and I'm interested in your opinion.

No. It is an electrostatic force that pushes the charge carriers. The voltage is the associated energy per unit of charge.
 
No. This is not a matter of opinion.

The electric and magnetic forces are related, but the potential leads to an electric field, not a magnetic one.

ok then does that mean that the magnetic force creates another force voltage or potential pressure ... which then pushes the electrons through the closed circuit because say within the alternator the magnetic force transforms the mechanical energy into the electric energy
 
Yes. The change in magnetic field causes an electric field (Faraday's law)
That's why the alternator does not generate anything when standing still :smile:

Why not start with a good source of information* about this and follow the established route? If you try to make up your own theory, starting with your present level of knowledge then you will not make progress. This topic is so well grounded in measurement and solid theory that there is no room for "opinion".
*A textbook or even the top few paragraphs in this link.

I understand and thank you for the answers but I was just wondering if what why called the magnetic force creating a new force voltage and these two forces in the combination transform the mechanical energy into the electrical energy

Why bother trying to re-state a perfectly formed description that is almost two hundred years old? It's called Electromagnetism because there are two fields involved and one field changing will generate the other.

sorry but i am not regretting anything i am say exactly as you yust with different words which are less complicated and easier to understand

why have one force and when magnets rotate why have two force and energy transformation mechanical to electrical

Please use complete sentences and initial upper case.

Easier to misunderstand, perhaps easier to think you understand when you don't, but not easier to understand.

I do not think that you are saying the same thing just with different words. Your question indicates that you do not understand Maxwell’s equations in any words. Maxwell’s equations etc. describe electromagnetism at a classical level. They describe the relationship between the voltage and the magnetic force.

I strongly encourage the deliberate study and use of the standard words. Sometimes the standard terminology is not ideal, but it is still important to know it to facilitate communication. If you are unwilling to do that, then the next best approach would be to stick with the math. Inventing your own terminology is not appropriate for PF.

"Excellent wise sentence " .You still have not explained to me what the difference between my claim and yours, of course, except ordinary names

You cannot be understanding the Maths if you make a statement like that. Do you seriously think that we do things the hard way just for fun? If you are so sure of yourself then you should try to derive some of the important facts that come from Maxwell without using Maxwell. That would be very impressive.

Perhaps the best response was written a century and a half ago:

'I don't know what you mean by "glory",' Alice said.

Humpty Dumpty smiled contemptuously. 'Of course you don't — till I tell you. I meant "there's a nice knock-down argument for you!"'

'But "glory" doesn't mean "a nice knock-down argument",' Alice objected.

'When I use a word,' Humpty Dumpty said, in rather a scornful tone, 'it means just what I choose it to mean — neither more nor less.'

If you want to communicate, it's best to stick with established vocabulary.

Your claim is ##V=q(v \times B)## whereas we claim ## -\nabla^2 V = \rho/\epsilon_0##

Voltage is not a force -- of any kind.
