Electromechanical relays

Can someone tell me if the coil on a relay will generate enough of a
magnetic field to cause noise on striplines that are running within the
printed circuit board? These striplines do not run beneath the relay nor
are there any microstip lines. The striplines are made up of copper traces
between copper reference planes, nothing ferrous in there at all. The
relay power is dc, but it does show some noise.
Thanks,
Walt Kreiger
