Yes it is artificially produced, but it works.
Of course it works, however it is not a true zero-gravity environment.
Our satellites and the ISS are also in 'artificial' zero gravity environments. They are subject to both gravity and centrifugal force. That is not the same as being in a true zero gravity environment. I doubt that we have had anything, ever, in a true zero gravity environment. It may not even be possible to find a place where there is no gravitational pull.
