When you apply a voltage, you have the peltier effect. The battery discharges at a rate dependant upon the resistance if the junction times the current flow. While the current flow does carry heat to one side of the junction. There is no Seebeck effect until the battery voltage drops below what...
Well yea...but...
Why would that ever happen in real life? Once you connect a battery, you get the peltier effect. Adding heat at this point won't change anything. You are trying to out think the process and you really shouldn't.
Mu metal will help but there is no way to totally shield a magnetic field. Magnetics Inc. sells it but it it expensive. Try making a shield out of a ferromagnetic metal and it will likely work about as well. A preformed iron or steel box with open ends will work pretty good.
The advantage of tin plating the copper is that it will not corrode when placed against aluminium. That is why it it tin plated.
Now the fact that it produces hydrogen in massive amounts, better than using plain water is just a plus. Enough to produce enough electricity to keep the reaction...
I called the tin / lead bar the anode because I made it positive electrically. The cathode was the copper foil. I used tin / lead since it is commonly used as solder and was available. I tried tin / silver and it works the same.
Bubbles occurred at an alarming rate at the copper cathode. It...
Yes, about any metal works well if it is an alternating field. If it is a fixed field then use mu-metal, or a ferromagnetic metal.
Any metal that is a conductor works well for alternating fields because an alternating field induces current in nearby conductors that it out of phase by 180...
Thought I might ask the pros here.
I found it difficult to buy tin plated copper and so I took a copper sheet, put it in distilled water with a bar of tin / lead and ran current through it. (anode was in tin / lead bar) The results were amazingly good. Looked like a professional job and I...
