Generation of artificial gravity by rotation I have been trying hard to understand how Artificial Gravity is produced by Rotating a satellite around its own axis. 
Thus far, I have understood (probably wrong) that as a satellite is spun, walls of satellite provide centripetal force to occupants and it acts as a normal reaction. However it is yet not clear to me with any site or book that with what acceleration it should spin. Of course whatever the centripetal acceleration is, it would provide a normal force to occupants (maybe little but it will) but I think since satellite is in free fall, occupants are accelerating at the same rate as satellite and therefore, in order to provide a normal reaction to the occupants the satellite ought to spin with same acceleration  as it is orbiting with around the Earth (definitely not $g$).
I am still confused whether I am right or wrong because I have read on this site that satellite should spin with acceleration equals $g$ so that a normal force is provided to occupants as is it on Earth.
 A: A spinning space station does not provide artificial gravity away from Earth, it provides artificial gravity toward the center of the station. The first effect the spinning surface has on an occupant is to provide a tangential acceleration through friction. Then, because the tangential direction runs into the wall, the occupant is "thrown against the wall" (similar to when you take a sharp turn in an automobile and are thrown to one side of the vehicle) and then the wall provides a normal force toward the center of rotation that simulates gravity.
The spinning surface doesn't generate an "artificial gravity" itself, in the sci-fi sense: if you were somehow able to get to the center and stop there, you could hover there because then it's the usual space station weightlessness (like on the ISS). Or if you could jump up and use a jet pack or whatnot to reverse your tangential velocity to zero, you could hover as the floor spins beneath you. Of course, then there would be no reason to call the floor "down" anymore; you're just floating in space, with a cylinder spinning around you.
