I think it is copper/zinc with a dielectric normal battery. He needs to wet the paper with the magnesium salt. Magnets do nothing.
Nope. Here's the proof. Build the same stack, but without the magnets. you will get the same voltage. It is a battery.
When soaked with a salt, yes.
Sodium salt would corrode the metals much faster than than magnesium salt. That is why he said to avoid sodium, but it would work.
