Yes. Placing a rotating magnet below it can generate a magnetic field that creates a spin in the suspended magnet. If the magnet is mounted on a low-friction axis, bringing an opposite pole toward one side of the magnet, then removing it, will add force to spin it for awhile.
It doesn't work like that. You can't make an electron have spin, remove its spin, or change the amount of its spin.What happens in a permanent magnet is that more electrons have their spin axis in one direction than in the opposite direction. Since the spin is associated with a magnetic field, that results in magnetism that can be observed externally.
Not all fans do need a coil and magnet - there are hand fans, punkah walla fans belt driven fans (as in your car) and Stirling engine fans that I can think of that do not need a coil or a magnet. It is only electrically driven fans that require a coil and magnet because they work on the principles of electromagnetism.
Magnet shaped like a horseshoe, so both the polarities are pointed the same way. They can be weak or strong magnets (my dad had a couple when we were kids... we put a broomstick in them and did chin-ups from the I-beam in the basement, because they were strong enough to hold a 12-year-old's weight easily). Here is a site with a picture of some: http://www.indigo.com/magnets/gphmgnts/chrome-steel-horseshoe-magnets.html
Each atom acts like a tiny magnet. When the atoms are aligned, the magnets produce magnetism. When an iron or nickel material comes near the magnet, its atoms align with the different pole facing the magnet. For example, if the magnet's atoms have the North side facing away, then the iron object will have the South side facing the magnet. So then they attract.
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.
The words to describe what you are asking is basically "is perpetual motion possible" The answer in reality is no. In a perfect environment with no friction, it could theoretically be possible. but the energy required to spin one magnet would be the exact amount of maximum energy that the other magnet can exert. Unfortunately friction in the air, and the bases where the magnets are positioned on also soak up the energy, therefor the magnet can never output enough force on the other magnet to keep it spinning.

No. Magnets create an electric feild, not electricity.However, when you spin a magnet inside a coil of wire (or you can spin the coil of wire instead), you will create an electrical current.

No.
Yes, magnet attraction is related to electron spin. Electrons possess a property called spin, which creates a magnetic moment. When electrons align their spins in the same direction, they create a magnetic field that can interact with other magnetic fields, leading to magnet attraction or repulsion.
The neutron has a spin of 1/2, which means it behaves like a tiny magnet with two possible orientations. This property is fundamental to understanding its interactions with magnetic fields and its role in particle physics.
YES, it is possible
The rotor (which is some type of magnet).
It would spin.
you spin it
