I've already answered this question and you might want to refer to that for more details. But here goes. \n\nA magnet is made of ferromagnetic materials, and will only attract ferromagnetic materials. These are iron, nickel and cobalt. Any alloy that contains one or more of those is ferromagnetic.\n\nThe metal forms tiny grains as it cools from a liquid to a solid, and within these tiny grains are even smaller regions called magnetic domains. Think of groups of atoms packed together. Unless a material is abolutely pure, there will be odd atoms of other elements and when the metal cools, they do not stack together absolutely correctly. If it is only a tiny amount of impurities, we do not notice the difference in terms of size, shape or weight.\n\nBut the domains are not lined up the same. Think of a bunch of guys just starting basic training. They are all milling around on the parade ground. But let's say that we heat the bar of metal until it is almost ready to melt and then subect it to a strong magnetic field (stick it inside the coil of a strong electromagnet, and let it cool that way.)\n\nNow they are all lined up the same way (just the way a bunch of paper clips will al line up when you pick them up with a magnet.) And when the metal cools and become solid once more, now they stay in that position. It is like a drill sergeant coming and yelling at the new recruits until they line up in formation. Now they are ready to take orders and get some useful work done.\n\nWhen the troops all line up and march the same way, you can see the result. They are more orderly, when they march along their feet all hit the ground at once, and they look unstoppable! \n\nIt is the same way with the magentic material. Each one of the individual atoms has its own magnetic field, but when they are all pointing in random directions, nothing useful can be done. Some are pointing one way, some the opposite way. They act against each other and their corporate effect cannot be felt.\n\nSo, now that the atoms within the domains are lined up together, and the metal has cooled and solidified into a solid bar again, the domains are lined up in formation. Now, they are all pointing in the same direction and we can feel the effects of the magnetic field even outside the magnet itself. The magnetic field reaches beyond the magnet and loops around in space until it reaches the other pole, forming a sort of circuit.\n\nOkay, now we have a magnet and we can understand why it attracts another magnet, because opposite poles attract. north attracts south and south attracts north. (No such thing as gay magnets! it's a law of nature!). \n\nBut why does it attract ordinary non-magnetized iron or steel?\n\nThat has to do with the fact that even though the metal is solid, and the atoms cannot flow away as in a liquid, the atoms are still free to rotate in place without moving from where they are.\n\nThink of the group of raw recruits before they go through their basic training. They are standing around. All of a sudden, they hear a loud noice. It is the drill sergeant yelling at them. All their heads turn in his direction! He has their attention. It is the same way with a magnet.\n\nWhen the magnetic field of a magnet acts on the atoms (iron, nickel or cobalt) of a piece of ferromagnetic alloy that has not yet been magentized, even though the atoms can't move from their spots, they rotate to face in the direction of the magnetic field. They temporarily act together, just as the domains inside the permanent magnet do. The fancy scientific name for this is 'magnetic induction'.\n\nNow, the temporary (induced) pole in the piece of metal is attracted to the permanent pole of the permanent magnet. They move together, because the tendency is for the magnetic field to travel as short a distance as possible, and a pole alwasy induces the opposite pole. The two together, so the magnetic field can travel across the shortest possible distance.\n\nWhen the

bring the magnets close to each other. If u feel any repulsion, that means u have tried joining opposite poles.\nWith this test u just come to know of the repulsive and attractive sides relative to a magnet. No qualitative nalysis of which is North pole and which is south cannot be done! But hey! If the bar magnet is painted red on one side, then that would be the north pole!

Possibly. The only metals that are ferromagnetic are iron, nickel, and cobalt. Selenium is a completely different element, so if it's pure selenium, it won't show up. \n\nHowever, the aztecs probably didn't have pure selenium - it likely contained some iron. So it would show up.

There are some natural magnets. For example, the mineral magnetite is magnetic, and is found in lodestones. \n\nIf you have a magnet, you can stroke a piece of metal (not all metals, but some) and magnetize it; that is, turn it into a magnet. You line up the magnetic domains when you stroke it so it has a net magnetic field. If you put a radio reciever nearby tuned to the right frequency, you can hear the domains flip as you do this; this is called the Barkhausen effect. \n\nThere are also electromagnets. Passing an electric current through a coiled wire wrapped around the right kind of metal (called a shunt) produces a magnet. This is the kind of magnet one finds in MRI machines.

My Mom who is in her 70's swears that the hematite is helping her, she had no other choice when she was told she could not take glucosamine, etc. I think it depends on the person...some people it helps and others it doesn't. \n\nMany report the great affects of magnets...and true hematite will stick to a magnet. The imitation does not.\n\nI have the magnetic bracelets and they don't affect my computer at all.

Metal of course.  You will attract any guy who has a magnetic personality.

Paramagnetic materials are attracted when subjected to an applied magnetic field. The alignment of the atomic dipoles with the magnetic field tends to strengthen it and is described by a relative magnetic permeability greater than unity (or, equivalently, a small positive magnetic susceptibility).\n\nParamagnetism requires that the atoms individually have permanent dipole moments even without an applied field, which typically implies a unpaired electrons in the atomic or molecular orbitals. In pure paramagnetism, these atomic dipoles do not interact with one another and are randomly oriented in the absence of an external field, resulting in zero net moment. If they do interact, they can spontaneously align or anti-align, resulting in ferromagnetism (permanent magnets) or antiferromagnetism, respectively. Paramagnetic behaviour can also be observed in ferromagnetic materials that are above their Curie temperature, and in antiferromagnets above their Neel temperature.\n\nIn atoms with no permanent dipole moment, e.g. for filled electron shells, a weak dipole moment can be induced in a direction anti-parallel to an applied field, an effect called diamagnetism. Paramagnetic materials also exhibit diamagnetism, but the latter effect is typically orders of magnitude weaker. Paramagnetic materials in magnetic fields will act like magnets but when the field is removed, thermal motion will quickly disrupt the magnetic alignment. In general paramagnetic effects are small (magnetic susceptibility of the order of 10−3 to 10−5).

Very much. Magnet has nothing to do with earth's magnetic north and south. It has it's own north and south and will very much attract like it does on earth. I think you are confused with compass which will not work in space with no north and south.

No.\n\nBut it can when it is heated.\n\nIf you heat a magnetic material above its Curie temperature, it depolarises and stops being magnetic.

Hey there:\n\nInteresting question, because a month ago, i stumbled upon a thrown away harddrive while walking my dog.  I desembled it while I was at home, and found inside it TWO EXTREMELY POWERFULL RARE EARTH MAGNETS.  Also, around on each side of these magnets, was a magnetic shield, that did not allow them to attract from one side, but yes from the other.  If I was you, look for any thrown away harddrive, they all have them, and you will also be getting an extremly powerfull magnet while you are at it.

Magnetism is caused by  electrical charges in motion. This is not necessarily something unique to electrical equipment, which is the case for electromagnetism, but also for permanent magnets. It is the motion of the electrons around the nuclei, and also the spin of the electrons, that cause the magnetism in a natural magnet. The magnetic field of Earth is believed to come from movements inside the planet, where oceans and rivers of melted metals exist.\n\nI can only think of two types of magnet; natural magnet and electro-magnet.

It depends on how powerful a magnet you use. To get a magnet to perform all of those tasks, it will need to be a really powerful one.

maybe using a magnet will help

Umm, your own source disputes your claim of no magnets:\n\nForm Wikipedia:\n\nObservations of the magnetic fields on Mars by the Mars Global Surveyor spacecraft have revealed that parts of the planet's crust have been magnetized. This magnetization has been compared to alternating bands found on the ocean floors of Earth. One theory, published in 1999 and reexamined in October 2005 with the help of the Mars Global Surveyor, is that these bands are evidence of the past operation of plate tectonics on Mars.[14]\n\nSo yes, a compass would work but not necessarily point to the north.

No. Things only respond to magnetic fields if they are paramagnetic, meaning they have an extra lone pair of electrons that aren't tied down. Glass is SiO2 (silicon dioxide, better known as quartz and sand), which doesn't have the lone pair required.
