does this flow effect work with the water analogy of electricity?

I had to google it. It seems like it's at least plausible that it might: https://pubs.acs.org/doi/pdf/10.1021/nl070935e

The circulator[1] is an analogous component in rf, it send the incident power from any port down to the next port, so you can take one port to be the bidirectional connection, and it splits the signal into transmit and receive connections.

Just realized if it did this would make a very simple rectifier. I guess you could test it by putting ends of a wire with a galvanometer on it to different parts of an antenna and see if you get a current.

This relies on inertia so probably not.

Inductance is similar to inertia in the water model of electricity.

Yes, but it's not directional. You don't get to make a T-joint of three coils and have the current follow the top bar as it's a straight line.

Diodes don't work based on inductance.

Diodes would be something along the lines of a check valve.
