The energy efficiency of water electrolysis was considerably improved under a high magnetic field. This was proved by measuring the cell voltage, the IR-drop, and the electrode potentials for the electrolysis which was galvanostatically operated in alkaline (4.46 and 0.36 M KOH) and acidic (0.05 M H2SO4) solutions. A large reduction in the cell voltage was achieved in a magnetic field, especially at a high current density. The decrease of the IR-drop, which was measured by the current interrupter method, depended on the concentration of electrolyte solutions. In a magnetic field, the oxygen overpotential was reduced more than the hydrogen overpotential.

Mark,

Oxygen is FERROUS. if you have a flask with liquid oxygen, you can use a magnet to "move" and "pick up" the oxygen in the flask much the same as iron filings.

try it with nitrogen..it doesn't work.

something to think on.....

Thanks Alaska,
sorry I miised you on skpe the otherday ..I will be home all this week.
I will leave any comments re magnatism to you and Bob as I know you both have considerable knowledge on the subject. I just posted what I did as I thought it was an interesting read.

the best I've seen is Shigeta Hasebe's us pat no 4747925, wherein he slaps a big ring magnet on either side of the tank to increase the lift force on the rising bubbles.

I've looked around but havent found anything bigger than 135mm, even tried a few speaker repair places but no luck.

you can visit the and type in 4747925 in the pat number search or download a pdf file from using the 474925 number again, its about a 520 kbit file size.
