I must strengthen my knowledge in the mathematical properties of signals, and would like to know the following thing:

* if I have a complex signal, written in magnitude and phase, it's like if I have 1 signal that holds 2 signal himself? I have this question because I have to do the inverse transformation of a signal in the frequency domain , that is complex and I have the magnitude and phase plot. Is it right that my phase, when I do the inverse- transform retards my signal ( the inverse transform of the magnitude) in the time domain? 
Thank you so much.. I have not on focus how the phase works yet

Thank you for the answer, I know what you have written... my question is: 
If I have one complex signal in the magnitude and phase form, do I have to consider magnitude and phase as two different signals? Look

The signal is written in magnitude with a complex exponential with the phase... when I do the inverse transform the exponential is in the time domain a delay ... and this it feels strange that one signal bring with him a delay ... it's like if phase is another signal , that retards the inverse transform of the magnitude.
I hope I have explained my question in the right way
