    anyone can explain how exactly magnetism and gravity works? like, at an atomic level.

    Exactly? that would be impossible. You can say the electronic particle follow spacetime distortions which make up fields themselves. You can say this ''movement'' is relative to the experience of magnetism itself. It is like having a wire around a magnetic. You move the wire with electrons in it, and it will experience magnetism. You move the magnetic, and it experinces the electronic force.

    The forces curve and swirve around each other in much the same way we are told to envision the curving paths around the poles on a magnet.

    I realized you said gravity, not electric force... but mentioned magnetism. Well, my explanation for magnetism goes. A for gravity, we envision the graviton being the mediator of the force. The graviton can move in linear paths like any boson of quantum physics, but become distorted upon the interaction of presence of matter causing curved paths in spacetime. The object of unifying gravity and magnetism would surprisingly be best said under gravito-electromagnetic equations, or GEM for short.

    As best as I can tell, gravitoelectromagnetism (also called gravitomagnetism) actually has nothing to do with electromagnetism. Instead, it's a part of general relativity that takes a form very similar to that for the equations of electromagnetism (Maxwell's equations). So that doesn't actually answer the original question.

    Now, I can't really answer it either, since I don't really understand it well enough, but, for electromagnetism, charged particles interact by exchanging virtual photons. What that means and how it works, I don't really know very well, but at least it's something you can look up. :P As for gravity, well, I don't know if anyone knows how that works on an atomic level.

    Gravitomagnetism is a model which must include a moment of electronic fields. As far as we can tell from a relativistic sense, electro and magneto forces are indestinguishable next to the movement of eiter objects. Gravity is harder to make use of this picture... gravity is a product of something which is ''there'' but also needs high energies for any coupling to be ''recognised''.

    This, this and the wiki disagree. There is no magnetism (or electromagnetism) in gravitomagnetism. It's only called that by way of analogy.

    This is getting off topic, btw, so if you want to continue arguing this, please make a new topic.

    But the absence of magnetism is the absence of electronic fields.

    Though, if wiki is what you cite, then i cannot deny the influence of more people of an expertize in the subject.

    What is an "electronic field"? No such thing exists. One suspects you mean electric field. This is an unbelievable error (twice repeated) for a so-called student of physics.

    Anyway, you are wrong. While it is true that every electric field induces a magnetic field, the converse is not true in general; only by the physical movement of a magnet in the presence of a conductor is an electric field induced.

    As a "student of physics" you will be able to explain in some detail the connection between my assertion and the presence of the time coordinate for the E field in Maxwell's equation, and its absence for the B field.

    Right?

    Bolded by me, and took you off ignore by then respect of John... Give me one good reason to suspect i should not have...? Your own words delight me a salad, never mind what you personally think.

    I also hope none of that was directed at me... let alone, none of that was what i said, so....

    Magnetism works by the intermolecular forces between atoms, essentially in a magnet the atoms all line up with the positive atoms north and the negative atoms south

    http://www.examstutor.com/chemistry/...ne_diagram.gif


    this gives an exccess magnetic charge that we see and although atomic forces seem too small to explain it, gekos stick to walls using the same principle





    Gravity cannot be explained at an atomic level, hell it can't be explained more indepth than 'the apple falls because the earth is bigger' we simply do not have the means to find out yet, there are many theorys and the Large Hadron Collider will prove/disprove the current leading theory of the 'Higgs Boson Particle'
    It's not how many questions you ask, but the answers you get - Booms

    This is the Acadamy of Science! we don't need to 'prove' anything!
