How can we measure this force which seems to be flowing through the wire and causing bubbles on the copper?

- When you dip electrodes in water, the positive cathode attracts the polar hydrogen, and vice versa with the anode and oxygen. This causes water molecules to break apart. The liberated hydrogen forms small bubbles at the cathode.(1 vote)
- If on the end of one wire we stick copper and on the other end zinc and put in vinegar ?

- How come when the alligators were not connected there was no bubbles on the wire and when the alligators connected there were bubbles on the wire?(1 vote)
- I watched the video on Discovery of Electromagnetism so the answer for how can we measure this force which seems to be flowing through the wire and causing bubbles on the copper?Is use a battery?(1 vote)
- What would happen to the Zn nail once the wires are connected?
Will the bubbles on copper wire still be there or would they vanish?(1 vote)
- If bubbles are produced on copper wire do they go off from zinc nail?(1 vote)
- I don't know the reason but If you will watch the video carefully then you can see that bubbles are still being produced on zinc..(1 vote)
