None of them, coz a magnetic field does not affect static charges.\n\nUnless that was the answer you were looking for, I get a feeling something is amiss in the question.

An electron is a "monopole".  The reason for it having but a single extending magnetic field is that one half of an electron is formed of magnetic lines and the other half is formed into mass.  The electric field of the electron forms the equatorial line.\n\nIn larger mass, that is formed of electrons, opposite fields are formed because of opposite spin lines forming at opposite ends of a magnet.\n\nTo see this on a larger scale, consider our planet.  It has the magnetic field it does because of its rotation.  Planet Venus is almost a twin to our planet, but it has almost no spin and no magnetic field.  Planet Jupiter, a large planet with great spin, has an intense magnetic field about it that it affects spacecraft that are too long in its presence.\n\nThere are "hemiforces" moving from the poles of our planet toward the equator (called Coriolis effect).  This energy increases as one moves from the pole toward the equator because of greater mass having greater spin.  When these forces meet at the equator, they are, in force, moving opposite each other.  When passing through the plane of our equator the energy moving through the plasma forms opposite existing fields.  It's always the same.  Where there is energy present, it must give evidence of its presence in some manner.

Any two magnetic fields will interact with each other. The same happens with the Earth's magnetic field and a magnet, although the Earths magnetic field density is very weak in comparison to a magnet. \nThe magnet will locally distort the Earths magnetic field, which can be seen by looking at a compass in just the Earth's magnetic field, then looking at the compass when a magnet is brought near.

I'm not sure anyone really "know" but there are many teltail clues.  Not all materials are magnetic except perhaps under very powerful magnetic fluxes (MRI's?) but all atoms of materials do have one or more electrons orbiting their nuclii.  We know that electrons can be directed by magnetic flux, perhaps in a TV picture tube, etc.  Therefore, the number and arrangements of electrons of the atoms differ and some create magnetic properties (dipoles or two different poles).  If an iron bar is heated to a high temperature all the iron atoms in the bar are permitted to spin around willy-nilly.  If the bar is then cooled while exposed to a strong magnetic flux (electromagnet?) all its dipoles will align uniformly with the external flux like the needles of compasses aligned with the earth's flux.  When cool, the magnet exhibits the combined strength of all the dipoles that were previously working against each other.  We know that atoms repel each other because of their electrons (and even their nuclii must be forced together to fuse because of protons) like basketballs with ballbearings at their centers, where the skins are made of rapidly orbitting electrons.  Whereas the basketballs would repel each other in any given positions, actual atoms in iron crystals repel directionally and they which can attract or repel a free electron.  The magnet has collectively directed their combined force.  If each dipole has a North and South pole, we would expect the entire magnet to also have a North and South pole, and for like poles to repel, just as in the individual dipoles.  Hope that helps a little.

It will align with whatever magnetic field it is closest to or align itself on a piece of metal. If it isn't close to either of these, it will point in any random direction.

the answer is probably b (I will get to the "probably" part later). the path the electron takes would be bent by the magnetic component of the field (producing a curve) and it will be pushed by the electric field changing the direction toward a specific direction (along the electric field), but movement will all take place in a plane which is along the original direction of propogation IF the electric and magnetic fields are at 90 degress to the original projection. \n\nFor different orientations of the fields, it is also possible to get helixes for the movement path, which do not apply to any of the answers.\n\nAlso, for specific initial velocities, electric and magnetic fields, it is  possible to obtain a straight path.\n\nIf the electromagnetic field is varying with time, there cannot be an answer to this question, since the path can be totally erratic.

I'm sorry, but the previous answer was very misleading.  First of all, an electron's spin does not give it its charge.  After all, neutrons spin yet they have zero electrical charge.  Its spin gives it a magnetic moment, which is subtly different from a magnetic field.\n\nA charged object such as an electron moving in any trajectory will create a magnetic field.  A charge moving in a helical path will create an approximation to a solenoidal magnetic field.  In current carrying wires, the electrons are moving collinearly with the electric field created due to the potential difference, i.e. in more or less a straight line.\n\nNow, why does the moving charge create the magnetic field in the first place?  A good way to explain it is with an example.\n\nSuppose you have 2 protons (+ charge) placed close to each other, the pair initially being stationary with respect to you.  You know what would happen right?  They would drift apart, repelled by their like positive charges.\n\nNow picture yourself running very fast, past those two protons.  If you run fast enough, the relativistic time dilation will make it appear, from your perspective, that the protons are drifting apart more slowly... as if some force is holding them back.  If you consider that you running very fast with respect to the protons is the same as the protons moving very fast with respect to you, you can see that the two moving charges are having an effect on each other which cannot be explained by their electric field strength alone.  This is what we call the magnetic field, essentially a relativistic distortion of the electric field due to time dilation.

I would say the strong nuclear force, that holds quarks together in protons and neutrons. This is the strongest if you add up all the individual forces in the universe, as it is present in every proton and neutron in every atom in the universe. If the strong force disappeared, the entire universe would instantly explode into fundamental particles.\n\nOn the other hand, on an everyday scale, the electromagnetic force is most noticeable (it is responsible for everyday forces between objects), and is stronger than gravity (by standing up the electromagnetic forces between atoms of your feet and the floor are overcoming the gravity of an entire planet.)

Electromagnetic fields. In the classical view, a charged particle experiences a magnetic force when it is at some non-zero velocity with respect to a magnetic field. This is in addition to any electric force from any electric field that is present.\nRelativity theory unites these two fields as it reveals that a magnetic field is just what an electric field "looks like" to a charged particle when there are non-zero relative velocities involved.\nQuantum field theory (specifically quantum electrodynamics aka QED) further simplifies this by viewing electromagnetic force interactions as exchanges of "virtual photons".\nAs was said before, depending on the scale of the system, any of the other 3 fundamental forces may non-negligibly affect the particle as well.

It will utilise quantum mechanics. At the subatomic level, matter behaves very differently to classical mechanics that we are familiar with in everyday life. The spin property of particles is not actually the particle spinning like a top, but is a term given to their angular momentum to help explain their interaction with each other.\n\nParticles can only spin in certain allowable directions, electrons have only 2 directions, other particles can have more. The ability to be in 2 spin states at once is due to uncertainty in that the particle could be in either state until it is observed and probability functions are used to describe its state.\n\nSimilarly a particle in a quantum well (a box with walls of electric potential) will move about with its energy in a fashion that can be described by its wave function. At any measurement it will be in a certain point (although with unknown momentum) but it will vary with every measurement.\n\nThese sorts of uncertainties are what are scientists are hoping to use in quantum mechanics. Calculations will actually be performed millions of times simultaneously providing varying results, but favourable probabilities will lead to the correct answer with immeasurably small innaccurary.\n\nPotential methods will utilise the spin magnetic moments of electrons, or the position of valence (outer) or free electrons moving between pairs of ions (charged atoms) accurately positioned in a semiconductor. There is still a lot of work required.

I hope you are familiar with atomic theory if not get familiar and come back to this. as an electron moves it creates a wake much like a boat moving through water this wake is called a magnetic line of force. if a nother electron is encountered by this wake it will be influenced by it like a surfer on a wave. an electromagnetic fiel is the area of influence of these waves. in most materials the electrons are moving in many different directions, hence the sum field is random and weak. however if most of the electrons are coerced into a uniform movement the individual lines become coherent and combine to provide a polarised field with a stronger magnetic influence moving this fiel across an object will cause the electrons in it to surf and produce an electric current. however these surfing electrons will produce a magnetic field that is the opposite of the field they are surfing on.

My favourite is the test done to prove the magnetic force of earth.  I do not remember who the scientist was but in the dome of St. Pauls's Cathedral in London UK, he suspended a rope from the highest point down to the ground where he had a level patch of sand.  A weighted point on the rope was just about able to touch the sand.  Sure enough, as time went on the rope began to move with the direction of the earth leaving evidence of stripes in the sand.

The pole in the north direction of earth is the south magnetic pole of earth's magnet.\n\nThe position of magnetic pole is changing but not the pole itself. If the pole cahnges then the magnetic needle in the compass will deflect in the opposite direction.

mm very interesting, yes, you see the subatomic particle has a mediaotian nucleus, this way induced in the heat of the radius of the positive electron makes the velocity of the Radiupositivum acelerate to almost the same speed as the particle inverse. This way, when the sub-nucleus reaches a temperature equal to the electron, the magnetic implosion "jumps start (like in a car) " the particle to have strenght and velocity, and the thing that makes is rotate is because the weight of the electron is always opposing the subnucleus.\n\nYou can see this ilustriated in the 1986 issue of Sports and Physics Illustrated. page 45\n\nHope is useful.
