Roughly speaking, there are only two options here: either a component reacts to the magnet, or it doesn't. This means that you can easily have a mixture of two substances that either both react to the magnet, or none of them reacts to it, so that you can't use the magnet to separate them.
There are several different ways and procedures of separating mixtures, though, some mixtures areirreversible, and can permanently be combined. A few ways of separating mixtures is through evaporation, filtration, sieving, gravity separation, distillation, condensation, froth flotation, magnetic separation, chromatography, and centrifuging (http://www.slideshare.net/brittgow/separating-mixtures-1247457). Also certain chemical reactions can separate mixtures, or create substances, i.e. acid+base=salt+water etc. (If this is no help I'm sorry just look up separating mixtures on Google).
Though it is hardly an official scientific designation, one sometimes refers to the north pole of a magnet as the "north seeking pole." This is, of course, in accordance with the characteristic of a compass.
1/2 true, when moved though a wire coil electricity is formed.
Yes, they can magnetise soft iron. Not sure about demagnetising though. I assume that if more than one or two were placed around the soft magnet, it could demagnetise it.. However, the soft iron would need to be 'hit' so that the poles in the iron can allign with the magnetic fields due to the electro magnet.
The second strongest building material is obsidian even though it can't get blown up.

Filteration
no it wont because copper is not a type of magnet even though it is a metal
The effective length of a magnet is the distance between the magnetic poles. It is always less than the geometric length of the magnet,though the actual relation between the two depends on the shape of the magnet.
In reality no. Though the size of a magnet does seem to affect the size of a magnetic field, it is in effect a ratio of volume, and does not change the effect of the magnetic field. The potential magnetism is not affected by size so much as composition of the magnet.
All solutions are mixtures but not all mixtures are solutions. A solution is a mixture of compounds where molecules of one compound are dissolved in another like salt(the solute) in water(the solvent). Other mixtures might not be solutions though, like sand and gravel, because one does not dissolve in the other
Yes though it isn't a completely accurate way to test it. If a magnet will stick to it then it is most likely gold plated, but if the magnet doesn't stick to it that doesn't mean that it is not plated just that the base metal isn't mahnetic.
Well, let's see. If I have a paper clip on a table and a magnet in my hand, and I slowly pass the magnet over the paper clip, the magnet in my hand is pulling the paper clip up with magnetism. If my magnet is close enough to the paper clip, the paper clip will jump up to the magnet ... even though the whole Earth is pulling it down with gravity.
magnets are usually composed of iron, though any polarizable metal will suffice.
England is part of Europe, though we have the English Channel separating us from Europe proper.

moons come from the mixtures of gasess from different planets,that is one theroey though .many belive it's mother nature.
