The lemon battery was the least amount of voltage with .200 volts.

This time replace the steel nail with the copper wire. Zinc and Copper make great battery terminals. Can you see why?

Hi Ian. Thank you for putting this together. It looks very thorough.
I am a physics teacher in a small school in Guatemala. The social studies
teacher sent me your instructable since he is studying the relevant period with
his middle school students. He asked me for assistance in creating a classroom
activity for his students. I am thinking that if we can light an LED, that
would be fun. Maybe we would wire some cells in series. I am most experienced
with the typical “lemon battery” activities. If we use an alkaline as you did,
instead of an acid, do we get a voltage right off the bat? I assume we would,
but your mention of charging made me wonder. Materials are very difficult to acquire
where we are. Would baking soda (Sodium bicarbonate) in water work? How about
just salt water as an electrolyte?

If you want to create a lemon battery to power something smaller, try it!

More speculation on uses of a homopolar motor.

You might research the time periods in which the Baghdad batteries were found, to see if magical movement or spinning of objects was one of the "features" of a religion or specific religious ceremony. If so, you might be able to get enough descriptions or find a drawing of one and see if a homopolar motor could be the mechanism.

The movement of the wire, and anything attached, would look like magic to most people of the period. Doing some mumbo jumbo, claiming you breathed life into an inanimate piece of wire and then putting the wire over the battery where it spun all during a ritual, would make you appear very powerful. Which would be worth a lot of effort to most priest of any time period.

A spiral wire shaped like a snake could be the most likely shape, since a snake's movement and shape would be somewhat similar to the shape of a spiral of wire spinning around the battery. The spinning is similar to how a snake climbs a vertical limb.

It is also possible that the wire might be in a shape that it would easy to attach streamers to.

With what you learned about how batteries generate electricity, why do you think that one type of produce made a stronger battery? Extra: If you have an LED (light-emitting diode) available, investigate how many lemonbatteries are ...

You can even use this trick to let your lemon battery runa low-voltage buzzer or turn a small motor (look for "solar cellmotors" from various mail order suppliers or Radio Shack.) As with the bulb, you mustcharge up the capacitor for many minutes, then use it to run your bulb ormotor for a few seconds.
It's not an ideal experiment, and it's hard to explain how work.

Resources: Oberlin College: Demonstration of lemon battery powering a buzzer. Alligator clips make this step easy. Fruits and vegetables require energy from the sun to grow and produce a harvest. Step 4: Measure the voltage drop between the two wires attached to the metal strips on the lemon and the potato. Make sure the rods do not touch each other. Make the slits are a few inches apart. What do you notice?

Results and Conclusion - Lemon Battery

One question may remain … why can’t we turn a light bulb on with this battery? The answer is, even if we connected several lemon batteries together (in series) to get the same voltage as in a D cell battery, the current we can get out of a lemon battery is just too small to light the bulb. But it is fun to try!

Replace the copper wire with the zinc nail. Touch a meter lead to each nail as shown in the photo. What happened with the lemon battery this time? Same voltage? Higher? Lower?

Go ahead and touch one of the meter leads to the nail and the other to the wire. What happens? The reading you see may be different from one lemon to another, and from one trial to the next. This is because the voltage difference we see depends on how far apart the terminals are, how well we make contact with the meter leads, how much and how strong the juice (our Electrolyte) is in each lemon, as well as other things that we cannot easily control in this experiment.
