Hello i am confuse in some point as i know that dc voltage is not given to coil because x=2pie*f*L and
in dc f=0 so reactance is zero and current go to infinite

then why we apply dc voltage to the relay and how dc can produce the magnetic field in the relay because

in dc there is no variation and inductor pass it without any effect and

no magnetic field produce when we apply dc to any inductor..?

please give me the answer of that question so that i can come out of my confusion.
