yes
Colour: black, opaque. Streak: black. Lustre: metallic or dull. Cleavage: none. Hardness: 5.5-6.5. Specific Gravity: 5.2. Its diagnostic feature is that it is highly magnetic.
Electrons in orbit around an atomic nucleus usually come in pairs, having opposite spin and hence having magnetic poles pointing in opposite directions, resulting in no net magnetism for the atom. Elemental iron has unpaired electrons making it magnetic. When the iron combines with sulphur, electrons from the iron atoms pair with those of sulphur atoms.
a photon cannot be deflected by an electric or magnetic field because it has no charge and no magnetic poles like elementary particles such as the electron
Technically impossible . In a rock , ferromagnetism can create poles , but not in atoms . Atoms cannot be magnetic . Molecules can be polar , which leads to Van der Waals links , but a region's molecule cannot become all lined in the same directions . http://www.youtube.com/watch?v=4VmMr9TWzY4 http://media-2.web.britannica.com/eb-media/65/265-004-9B256ADC.gif Pretty simple , as a matter of fact .
No Scott a non-magnetic collar cannot be magnetized.
Gravity and magnetism are inherently different forces. One cannot be the other.
Im not sure if this is the correct answer but its my thought that for magnetism to work there must be a magnetic field. Not all celestial beings have a magnetic field allowing for a magnetic attraction therefore magnetism cannot be the answer to the gravitational problem of space flight though it is also my thought that a series of motor driven gyroscopes might hold an answer.
Magnetic fields can be blocked. Magnetic fields cannot penetrate a superconductor, and regions can be shielded from magnetic fields using ferromagnetic materials.
The magnetic materials which can magnetise and de-magnetise easily are called "soft magnetic materials" example:-ferrites,iron-cobalt alloy. The magnetic materials which cannot magnetise and de-magnetise easily are called "hard magnetic materials" example:-aluminium(al),nickel-cobalt alloy.
Yes, magnetism is a property of iron. Unfortunately, I cannot explain the physics behind it (yet). However, it has to do with electron pairing and whatnot...there are good sites regarding magnetism that could help you with that.

Yes, an electric current traveling through a wire generates a magnetic field. There is no way that it cannot do this.

Such materials through which you can see are called transparent materials. As for example-glass. Such materials through which you cannot see are called opaque materials. As for example- wood
The magnetic field can provide a force because it can change the velocity of charged particles (through the so-called Lorentz force), and a change in velocity means the presence of a force. Magnetic fields cannot do any work however, so they cannot change a particle's speed, only its direction. In the grander scheme of things the magnetic force is part of the electromagnetic force, which is one of the four fundamental forces in nature.
