You can attach a string to a foam ball/plunger type thing and then suck it through with a vacuum from the other side. Then, fix your wire to the string and pull it back in the other direction.
A plastic bag tied to pulling twine works really well and is less likely to get stuck than a ball or plunger. I always leave a length of twine in my conduits so I only have to use the vacuum method once.
Indeed the plastic bag trick works very very well in a lot of different use cases. I was able to pull twine over 500 feet with this technique while doing my driveway conduits.
