Does digital output of the IR sensor module change due to magnetic flux??

I am designing a robot which can move on iron wall and also follow a white line in black background. I made a wheel by fixing magnets around it and the IR modules are fixed near the magnetic wheel. The robot run according to the program but IR modules take some time to response. Therefore, i have a doubt that the magnetic flux disturbs the digital value. So if anyone have a answer, please fill me in with.

Thank you.

Should not have an effect unless the magnets are moving very fast, in which case they could induce small currents in the circuit. Seems unlikely this is the case.
