Best source for magnesium?

    Ok. So now I want to start looking for sources of magnesium to make a
    homemade wet cell. Preferably the magnesium would be in strips. Are there any
    items in a hardware store which would be made out of magnesium?
    How about in a camping store?
    Or grocery store?

    Yes, there are places where you can get it. Explain more about the wet cell
    you wish to make and maybe I can lead you to a source.

    I would like to make a simple tabletop experiment using vinegar, and copper
    and magnesium for the electrodes. It could light an LED or a small computer
    fan or something similar.

    I would like a source of magnesium local to me so I don't have to pay
    shipping. So I'm looking for things made of magnesium which I might find in a
    hardware store, grocery store, etc. I live in a big city but I'm not sure
    where to get small amounts (relative to industrial size amounts) of magnesium
    strips or sheets.

    Go to www.campmor.com
    Search for item number 23131.
    Take a look at the resulting small block of magnesium.

    Have Fun,

    Joe

    Since you say you live in a big city, you must have access to the
    'Yellow Pages' which will, with no doubt, lead you to suppliers of
    metals.

    Magnesium bearing products (from which you can easily extract the
    magnesium) aren't something you're likely to run across in your
    local grocery or hardware stores, so your best bet would be to
    contact vendors who can supply elemental magnesium in the form of
    wire, rod, sheet, or ingot.
     
  6. Availability of magnesium metal from retailers is low. Probably from
    liability issues due to usefulness for incendiary devices, homebrew
    pyrotechnics, homebrew rocket propellants and homebrew explosives.

    The most electropositive metal commonly available to homebrewers is
    aluminum, and that has issues of forming insulating oxides. After that is
    zinc - hackable from non-alkaline ordinary batteries such as "heavy duty"
    ones like many dollar store ones. Just consider that such batteries also
    have manganese dioxide, which severely stains carpets and clothing (but is
    dissolved by many acids), and is also a mild oxidizing agent that has a
    major tendency to oxidize many metals especially if moisture is
    present (which is why it is used in many disposable batteries). Just keep
    this in mind!

  7. Make a few cells with electrodes of copper and a
    more-electropositive-than-hydrogen but easily available metal such as
    aluminum, zinc or iron.
    So your cells may only produce 3/4 of a volt, maybe .4-.5 volt with
    iron.

    I would not get my hopes up of having science-fair-style homebrew cells
    getting a motor to turn. But a few in series should have no problem
    lighting an LED. Could take 8 or so cells with more compromised choice of
    metals and a white, blue, or non-yellowish-green LED.

    If you need a light source with independence from power failures and from
    commercial availability of batteries, get a "shake" flashlight. And avoid
    the fake $2 versions that I have seen at some dollar stores.

    Strong oxidizing agent! Be sure to NOT use hydrochloric acid on that stuff,
    'else you'll get chlorine gas in proportion to the MnO2.

    It will remove it nicely, though. Along with any color the carpet was
    supposed to have...

    Magnesium: you can find rods and blocks for - what else, anodes -- at a
    variety of places (though I haven't checked). Water heaters, steel boats,
    etc., if it has water in it, it probably wants an anode. Sheet or any other
    specific form (bar of a particular dimension, etc.) you'll have to find a
    metal supplier who carries it.

    Look in the yellow pages for scientific supplies or specialty metals
    suppliers. A quick google was instructive:

    Hi Don! Love your lighting FAQ.

    I believe you when you say the Dollar store shake lights are cheap. But I was
    wondering, how are they cheap? Do they use cheapo NiCd batteries?

    Typically an industrial supplier will not sell small lots like I am looking
    for, but only in larger lots, say 100 lbs or larger.

    Even recyclers here in my town will only take metals if you have 100 lbs or
    more. And I'm talking about giving them FREE metal.

  14. At least some $2 versions that I saw at some dollar stores have fake
    magnets, coild with leads shorted together, and the only energy storing
    device being a pair of CR2032 cells.

    Two that I have seen do not even have real magnets in them, just a chunk of
    iron. The batteries run down and that is it for the light.

    no, not even that. they're shakeable, but the shake has no effect.

    Plumbing Suppliers carry consume-able magnesium rods that are dropped
    into Hot Water tanks to reduce corrosion. Sailboats and pleasure craft
    use a Magnesium Anode to reduce Electrolytic damage. Welding Suppliers
    might have some sort of magnesium welding rods. Diving suppliers may
    have access to Magnesium Flares for Underwater work.
