You will see this at once when you realize something has to hold these two poles together. Or to keep them apart! The platform, the base, the foundation under the two poles MUST be there also. Otherwise the two poles would not interchange electricity. They would get too far apart or too close together.
Also there is another thingit is what generates the electricity in order for it to flow or exchange between two poles. This could be a magnet circling between them or a coal fire driving a steam engine to make the magnet circle about.
There would therefore be no exchange of current between two poles unless they were (a) held apart and (b) being influenced by an agitating magnet.
Now you may or may not be a scholar of physics. But to understand this we will take a human example. For this is the useful discovery.
