A Battery In A Magnetic Field

First off, thanks to all who guided me on the prev. topic of battery
combinations for odd voltages. Next, i just have a minor question
probably of little consequence. Might make for a fun discussion,
though.

I'm about to build the small amplifier and mount it with a cheapo 6"x9"
4-ohm speaker in a Rubbermaid storage tub. No I'm not expecting
stellar performance, it's just a "toy" :-D Anyways, while trying to
determine the best place to mount the battery, i took the cheesy route
and just stuck it onto the speaker magnet.

The back of the speaker magnet is not electrically "live" in any way,
and this is a normal-everday 9V. Though the effects are probably very
negligible, what sort of influence on the electrochemical reaction
within the battery would you propose the magnetic field may cause?

Just curious, not important, and thanks always. :)

Nothing of any significance at the level of "zoom" you're talking.
"Zoomed in" to the point where chemical reactions "become visible", it's
at least *possible*, even if not particularly *likely*, that the
magnetic field would tend to cause some sort of "clumping", or perhaps
"aligning" of the ingredients in the battery due to possible differing
amounts of susceptibility to magnetic influences, but I wouldn't expect
to see such a thing (assuming it happens at all) causing any observable
effect in the overall "batteries make volts" view.
Just curious, not important, and thanks always. :)

Interesting question, even though it would seem to me that the answer
would be of little or no actual importance under real-world conditions.
Perhaps in a lab environment such as "trying to build molecules an atom
at a time" such a consideration would be crucial, but for your purposes,
any effect it has would most likely be so small that it probably can't
even be detected, let alone measured.

"Clumping" could be prevented by periodically rotating the batt, if
"clumping" existed in appreciable amounts. That *was* a good
question, though. My mother told me that a magnet would kill a
battery. Not sure where she got that uninformed bs, but it's
conceivable that others have heard the same, so it's good to dispel
such myths.

Don't sweat what? The battery? The speaker? The asking questions?
Your accusation that i have been smoking Si? :)

Oh I know.... any effect would be completely negligible, particularly
for this application. The clumping and aligning is what i was
visualizing, but i'm sure that the electrons would get pulled out of
this arrangement just the same when I threw the switch and turned the
circuit on.

I thought it was an interesting question :)

Smoking Si--> burning silicon based electronic components but that was
from another day when (you) we were joking with the OP of that thread. I
though most would understand the slightly obscure jest. But then I though
that was directed to Rich as it followed on of his replies.

To the OP of this thread, "Don't sweat it" means that it is okay to let the
battery hang from the speaker magnet. I've done that myself and it cause
no problems.

It is an interesting question reminescent of the arguments regarding storage
of
a car battery on a concrete surface and their apparent rapid discharge
having
done so.

Lighten up!

Hey, I've heard that's good shit, man! Lemme know if you find enough to
spare so I can try some! :)

Yep, that's pretty much what I'd expect, too.

Indeed. Now one needs to figure out if it's a question that has an
answer with any meaning! :)

up!

Of course! My mention of that above was completely tongue-in-cheek :)
Sorry if i seemed as if i were miffed about it, as that's not the
case... I'm typically easy-going and am quick to enjoy
jokes/puns/humour, etc... (after all, i was talking about eating
capacitors and soldering antidepressants).. It's cool man.. ;-)
car battery on a concrete surface

I've heard this one from a lot of people, but in each case i've asked
why that would happen. Nobody could explain it, they were just
repeating what they had heard. Sure enough, at the service station i
worked at several years ago there was a set of wooden "battery charging
trays" for keeping the batteries off the concrete shop floor while
charging or storing. When we had more than 4 batteries the shop
manager would set the batteries on metal coat hangers, as if the whole
1/8" of *STEEL* would make all the difference in the world....

I always thought this was B.S. but I've never had an otherwise healthy
car battery and properly calibrated concrete surface that i could spare
for a day or so to try it out. I could be wrong....

Oh man!!! Its got some epoxy and phenolic mixed in, Wait!!! I have
a 4" wafer of the pure stuff....monolithic, polished smooth. It'll cost
you though!!!! 1,0,0 crystal alignment so it snaps straight!!!

Ha! Hangers huh? Lets send him to electricity 101! Maybe the deal
with car batteries revolves around the cold soaking effect of sitting
on a slab. Then again, it could be the acid etching the concrete that
was the real reason this myth got started.

I took the battery from my neighbors car and her to a shop so as to test the
battery and to get a replacement with the exchange. I discovered that her
old battery had leaked on my carpeting in the hatchback area. The color was
okay but the plastic fibers had reacted and were clumped as if they were
glued.
I never did figure that out but now I have a liner that things like
batteries would
be placed upon.

Ooooooooooohhhhhh! Uncut! Wow! All I've ever seen was the stuff that was
already stepped on two or three times before it got to me. Yours has got
to be some seriously quality stuff, man!

How much ya want for just a taste?

I was going to say, since the case of the battery is clearly steel, the
magnetic field doesn't even get through it into the battery's guts anyway.

It's like the Shroud of Turin, a priceless relic! You can look and drool

Your late man, you gonna have to remember from yesterday! I though
you were strangely quiet. We're just screwing around.

My understanding is that the idea goes back to the era when batteries had
wooden cases. The concrete surface would draw moisture to the batteries.
Since lead acid batteries are wet inside anyway they must of been lined
someway. ON the otherhand it most likely has always been BS.

The old batteries were lined with an asphaltic/tar coating.
The wood still had moisture/electrolyte soaked into it and
was partially conductive. When set on the ground there was
enough conductivity to allow the battery to discharge
over time. With a modern battery that's clean that wouldn't
be a problem at all, witness the metal racks that batteries
are commonly stored on at battery stores.

That's what I remember reading at one time, anyway...
