Jan 28, 2016 at 17:36 comment added busukxuan @XCIX I just edited the first paragraph to explain a little bit more. Not sure if it helps since you probably already understood that from the comments. Just noticed some activity back here so I came back and see, and suddenly felt it'd be better if I edited the stuff into the answer.

Expanded 1st paragraph a little
Jan 15, 2016 at 21:13 comment added busukxuan You can say that. However I think in this case I would just say that "a force exists between the wire and the solenoid". In your case anyway, I don't think it is even necessary to apply the third law of motion because it is not collision. The law is only need in classical mechanics because the phenomenon cannot be explained by electromagnetic interactions, which are out of the scope of classical mechanics.
