    The title is wrong, it is ment to say : Can (if the body is voltage) produce an EMfield that would be unique.


    Given a conductor produces an EMfield if electrons move with the voltage (conductor) to the start of a coil or load, and turn to neutrons after they have passed through the coil or load, is it possible if a body where to be the conductor (nano volt rated conductor) could electrons move with it (voltage) until there are no longer any static atoms left in the body for the current to move (zero matter)? For example if there are fewer cells making the absorption of energy possible (dead body)?

    Absorption, now there's a funny word you guys use which I had to reasearch!

    absorbtion

    Sticking to the question, if we did produce an emf and we could see it like a baby 4d scan would everyone give off a unique field given we are all a variety of different voltages having starting points (heads) and finishing points (feet). The direction of electrons is dictated by voltage and EMfield are relative to one another. I have learned that the Emfield seems to work better when it is balanced with the voltage.

    Your new title makes no sense. How can a body be a voltage? There is nothing unique about voltage. Electrons do no turn to neutrons. There is no such thing as a nano volt rated conductor. Where are you getting all this nonsense?

    I have asked for it to be deleted, for now i'll post in the general discussion till I am 100% confident about emf emfield, voltage, current etc etc.

    I hope so, I think i've got it, if you could answer me this question I'll be closer.

    Do atoms (building blocks of everything) have a certain given level of EMfield and voltage and resistance?

    Resistance is property of bulk materials. It depends, in part, on the way the atoms bond to form that material. This is because it is electrons that are responsible for bonding atoms to one another. For some types of materials (e.g. metals) the electrons are free enough to move and allow current to flow.

    An electromagnetic field is caused by the movement of charge and so is not a property of individual atoms.

    Agreed the EMfield is produced by the movement of electrons within an atom jumping from atom to atom by static discharge and charge if I am not mistaken? So with out voltage movement of electrons is impoosible and thus making it impossible for a EMfield to appear?

    Is that anywhere near?

    Close. In a conductor the electrons don't really jump from atom to atom; they are already "floating around freely" (that is not strictly accurate but near enough at this level) so there is no "static discharge and charge". It is better to think of them like a gas of electrons around the atoms. They can be pushed one way or the other by an applied voltage.

    But you are absolutely right, a voltage is required to make the electrons move. This flow of current will generate a magnetic field.

    Note that without a voltage, electrons can still move around from one atom to another but this will be random. There will be no overall movement in any direction and so no current and no magnetic field.

    Hey hey, told you I would eventually get there!

    On that note then would I be able to say the more gas (free electrons) around the atom the voltage and EMfied will be greater thus making better for EMforce in the long run?

    Remember that voltage is something applied externally: the "pressure" from a battery or other source.

    The strength of the generated field depends on the current. As we see from Ohm's law this depends on the voltage and the resistance. You can think of resistance decreasing because there are more free electrons (but it is much more complicated than that). This can lead to more current and hence more field.

    The force generated by the field then depends on the strength (and rate of change) of the field (see above) and the charge/magnetism of the object being acted on by the field and the velocity of the object.

    It is all very relevant and fascinating at the same time. So voltage is the pressure which comes from the EMfield and the better the conductor the more pressure it can handle from the EMfield?

    andythomasthekey, I'm not too clear on what you're asking here. As the others are rightly dealing with the basics of your post, I'm just going to jump right in and partly answer your bigger question.


    The separation of charge across biological membranes is of fundamental importance to the maintenance and functioning of living organisms. There are electrochemical gradients (measured in millivolts) and electromotive forces (the proton motive force, or pmf) involved in both respiration and photosynthesis. Similar, but different, electrochemical processes are part of the process by which neurons communicate with each other.

    If you want to put it crudely, then you can say that electrical phenomena are very, very important in biology. Weak magnetic fields are likely to be produced by some biological processes.

    I've no idea about measuring them as "fingerprints" though.

    Yes ignor the title, I worded it wrong and still trying to think of the correct way to ask it.

    If man can make EMfield and voltage by using a generator creating the field to create the voltage to give rise to EMforce, then is the world just a giant battery? Given the EMfield around it, the voltage being everything withing it and the earths core spinning around procuding the EMforce?

    And and the finger print would be a unique signiture given to every individual displayed by their EMfield (if it could be measured accuratly), like a dna test..

    Not really. Forget the field. It isn't relevant and it is quite hard to understand fully (which is why they teach the hugely simplified version at school).

    Voltage is the "pressure" applied to the end of the conductor (pipe). The better the conductor the more current can flow.

    You can only begin to think about moving on to considering fields when you have fully understood the basics of voltage and current...

    The Earth's rotating core results in the Earth having a magnetic field. This magnetic field could generate a very small current in a moving conductor.

    However, I'm really not sure what you are trying to ask. But I think the answer is probably no.

    I think I worded it incorrectly again. What I should have said is this.


    If man can make EMfield and voltage by using a generator creating the field to create the voltage to give rise to EMforce and current, then is the world just a giant battery? Given the EMfield and voltage surround the earth and they are present everywhere, the conductor being the elements which make up earth and the earth spining around produces the EMforce which produces the Current?


    Is it that the faster the earth spins more pressure from the EMfield and voltage is made and from that will higher consentrations of Radiation be made?

    Not really. For one thing, the Earth's magnetic field is incredibly weak. Pick up a paper clip; can you feel it pulling towards the North pole? For another, most of the Earth is not a good conductor. Also, a conductor moving with the Earth wouldn't be moving through the field. So I don't really know what you are imagining. But I think "no" is a pretty safe answer.

    I guess if you were to spin a coil of wire really quickly in the Earth's magnetic field it would generate a tiny current. I'm not going to work it out, but I'm pretty sure it would be Very SmallTM.

    If the earth was a complex structure (All of the elements in the right order place and temperature) and the EMfield and voltage worked in perfect harmony with the elements (conductor) and the spin of earth is at the right speed would it be right to say that current is in everything but we just cannot measure it as we are bound by our limits - time and power.

    In other words every element in earth is a conductor and at the same time a resistor?
