The coil will produce an alternating electric current.

cutting through magnetic lines of force produce electric current.
Magnets are used in generators. A magnet is rotated by something, e.g. a wind turbine, and the magnet turns inside a copper coil which generates electricity. It is the opposite of a motor.
One of the laws of physics is that when a conductor moves in a magnetic field a current is induced in that conductor. If you then coil that conductor you effectively end up with several conductors and you'll get more current. Incidentally, you might be better of rotating the coil between the poles of a single magnet (a horseshoe type) rather than between two magnets as you've said in your question, because the two may cancel their magnetic fields out, depending on how they are positioned, whereas one won't.AnswerIt's voltage, NOT current, that is induced into a conductor. Current , resulting from this induced voltage, will only flow providing the conductor forms a complete circuit.
"electro magnets" are magnetic ONLY when electricity travels through a coil of wire surrounding them. "Magnets", as you state it, are permanent magnets and remain so independent of and not dependent upon any additional electrical charge.

A copper wire coil is rotated at speed in a magnetic field, to cause electrons to move. This is the electric current. The stronger the magnets and/or thicker the copper coil, the more current is produced

Rotate a coil of copper wire between two magnets.

Magnets would have magnetic flux around. As a coil linked with this magnetic flux is rotated such that the flux would change then an electro motive force is induced. This is the way in which generator functions.
Permanent magnets are bar magnets or horse shoe magnets which has magnetism at all times. But non permanent also known as temporary magnets are usually electromagnets which would have magnetism only when current flows through the coil that surrounds it.
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.
Yes, only relative motion between the coil and the magnetic field is important.
the force of objects being attracted by magnets. the coils or solenoids act as magnets and the projectile (which must be able to attract to magnets, often iron or steel is used) is attracted to the coils. but when the projectile reaches the coil the coil must be turned off so the projectile keeps going instead of stopping at the coil.
