Does the distance between the copper and zinc electrodes matter? What happens to the deflection when we hold them close vs. far apart? Why is there a difference? Created by Brit Cruise.

- It is something like if the electrodes are closer, more current passes per unit time and so magnetic field is stronger?(15 votes)

He never says where he is, although I'm going to assume somewhere in CA.(2 votes)
- what happens if the electrodes touch?(1 vote)
- nothing since their charges are both neutralised by the "metals" this would lead to no voltage differentiation so the copass would go back to what is true north(2 votes)
- At0:52What is making them move closer and further? What is with the wire or water?(1 vote)
- The closer the two electrodes are, the stronger the magnetic field is??(1 vote)
- Yeah the stronger the electrodes are, the stronger the magnetic field induced by the current, so there is a greater angle of deflection on the compass(1 vote)
- does it have to be a plastic cup or any type ?(1 vote)
