Why are some materials magnetic and others are non-magnetic?
Almost all magnetism is caused by electrons.Individual electrons have an intrinsic magnetic moment.In an atom, the electron's angular motion around the nucleus also causes a magnetic moment.Since all solid materials are composed of atoms and include electrons, the question becomes: why aren't all materials magnetic?Many atoms only have paired electrons, with the intrinsic magnetic moment of each electron cancelled out by the intrinsic magnetic moment of its paired electron.Many atoms only have "filled sub-shells", which have zero net angular motion.Atoms with either unpaired electrons, or unfilled sub-shells, or both, are inherently magnetic. However, in many materials, the magnetic moments of these atoms point in random directions, so they cancel out and the bulk material is nonmagnetic.It is to do with the pairing of electrons and their dipoles. Basically metals with uneven electrons or half shells are magnetic. Three main metals that are Iron, Cobolt and Nickel. With Iron being the main one.Hope this helps! =]
How are magnetic domains arranged differently in a magnetized material and in a material that is not magnetized?
The magnetic domains of an unmagnetized material will be pointing in random directions, which is why it is appearing to me unmagnetized. In a magnetized material, they move from north to south.
How is a magnetic field produced in a atom?
Simple Answer:An isolated atom has three sources for a magnetic field, the electron motion, the electrons' intrinsic magnetic moment and the nuclear magnetic moment.Explanation:First, the electrons around the atom are in motion and if there is a net circulating flow (i.e. a nonzero angular momentum) then the motion of the electrons is a current that produces a magnetic field in basically the same process that any current produces a magnetic field.Second, the electron itself has a magnetic property as a particle called the magnetic moment. The magnetic moment of the particle effectively makes it a tiny permanent magnet. (Other elementary particles have this property also.) The electrons in an atom can be arranged so that the magnetic fields of the individual electrons' magnetic moments add together or cancel each other out. If they do not totally cancel each other out, the atom as a whole then has the property of a tiny magnet. If arranged in a bulk form, like an iron magnet, these electrons can be the primary source of the permanent magnetic field of a material.Third, the nucleus of an atom is also made up of particles with an intrinsic magnetic moment, just as the electron is. In particular, the protons have a large magnetic contribution. It is not often the case that the nuclei of atoms spontaneously align with the nuclei of other atoms to produce a net permanent magnetization of a material, but it is a technologically important characteristic, e.g. for magnetic resonance imaging (MRI).
How is a magnetic field produced in an atom?
This depends if they are charged or neutral and if they are moving or not. A: If they are not moving then nothing usually and if they are neutral nothing. B: If they are charged and moving then they begin to accelerate in the direction of the magnetic field. C: If the object is a magnetic object for instance Iron that shares its electrons metallically then it will feel a acceleration in the direction of the magnetic field all other object will feel nothing.
How is an electromgnet and a bar magnet different?
The bar magnet is what is termed a permanent magnet . This means that it is "always on" and can be used to do things like pick up paper clips. The electromagnet is created by winding a coil of wire about a ferromagnetic core and running a direct current through that coil. Only when the current is flowing will the electromagnet be operating. With the current switched off, the magnetic field around the coil of wire disappears, and the power of the electromagnetic disappears as well.There are some "fine points" associated with a further extension of this post, but the basic answer to the question is as written.A bar magnet is made from magnet materials and has a magnetic field at all times. An electromagnetic is not naturally magnet and only has a magnetic field when electricity is passed through it.
What happens when a magnetic domain point in different derications?
they cancel each other out.
What is magnetism produced by?
Magnetism is produced by the alignment and movement of electric charges, specifically electrons, within a material. In some materials, such as iron, nickel, and cobalt, the alignment of these charges creates a net magnetic field that can attract or repel other magnetic materials.
Why is there magnetism on earth?
All magnetism is due to circulating electric currents. In magnetic materials the magnetism is produced by electrons orbiting within the atoms; In most substances the magnetic effects of different electrons cancel each other out, but in some, such as iron, a net magnetic field can be induced by aligning the atoms.
What do scientists think causes magnetism?

The magnetic fields of all the atoms in a magnetic domain?

If every iron atom is a tiny magnet why aren't all iron materials themselves magnets?
The magnetic fields produced by each and atom is not aligned in the same direction and have random direction and thus they cancel each others magnetic field and thus the iron does not behave like a magnet
How are magnetic domains arranged in magnetic material?
They are arranged randomly so ultimate magnetic effect is zero. But in some material they do not cancel and have some +ve or -ve value.

What parts of an atom produce magnetism?
Every atom with the electron(s) revolving - or "spining" - around the atom's nucleus is a little magnet itself. Electrons of all atoms in a piece of material revolve (spin) in all possible directions, the magnetic field produced be each atom-magnet cancel each other and there is no general magnetic field in the material. If under the influence of an external magnetic flux picture does not change the material is said to be non-magnetic. On the contrary, if under the influence of the external magnetic flux the electrons spinning allign in the direction of the flux, the magnetic field of every atom allign too and produce a general magnetic field - the material is magnetic.

Why are unpaired electrons more significant than paired electrons in terms of magnetic properties?
I wouldn't say they are 'more significant' but if they are paired their magnetic moments cancel each other out and if they are not paired there is a net magnetic moment.
