Why is it still giving a wave output

this is a weird circuit. It still has a wave output when the voltage source is a square wave source. Is because of capacitance or current or something else, I think that it is capacitance

Your amplifier is amplifying the difference between its two inputs. In your circuit this is a square wave.

I used wave source before square wave source

U have set pos input higher with 1ms wave.. so when ever pos inp become higher than neg inp then op will become high and when vice versa then low.. in this ckt its happening in same way..

So, what we are saying is that your circuit is acting exactly how it should. If this still looks wrong to you then Google to learn a bit more about op amps :-)

Actually since your opamp output is being band passed filtered by your capacitor and the inductance of your relay, so the dc component and the high frequency components presented on the transitions of the square wave that would exist are filtered out. Giving out a zero centred ( no dc component ) and with "smooth" transitions wave as you see

(SimpleAndComplex248558) well a capacitor filter and stores, so it changes frequency of wave when in charge, but capacitors release the same thing that happens to its current and voltage before, that eventually means that it should become a square wave again.
