how does magnetic arthritis jewelry work, how can you tell the difference between good and bad quality beads?

Make sure it has a strong enough magnet to stick on the refrigerator (or such)  without falling or sliding. The magnet pull needs to be strong (too many are not). And you should have something on each hand to balance (or toes-wrist ect). The necklace should hang some in back unless it is small enough. Even though they say water proof try not (if it does do not worry) to water it for long periods. Always were at night-supposedly at a relax state you get more from magnet and more even results. Hope that helps.

The process is as follows - \n\nA good appraiser will clean your jewelry, point out needed repairs, and test the metal for content and karatage (fineness of metal). \nGemstones will be tested for authenticity, measured, and their weights estimated; they will be graded, plotted and/or Gemprinted as appropriate. \nYou jewelry will be photographed. \nThe appropriate market value will be assigned according to the type of appraisal. A cover letter will explain the appraisal, including its correct use.

The alloying metal in sterling silver is often copper.  As an experiment, try wearing a copper bracelet for a bit and see if you show allergy to that.  Painting the necklace links with clear nail polish, as other responders have suggested, could help.

Who knows? People who believe they are hypersensitive to electric fields are ironically also more likely than others to believe magnetic bracelets can cure things.  The fact is, there is no real difference between electrical & magnetic fields, they are manifestations of the same thing.

It's important to pay close attention to the metal that the earrings are made of, and that they be very clean (isopropyl alcohol) when they go in, and that they not be left in more than 24 hours without cleaning again.\n\nMost people find 14 ct. or higher gold to be the least irritating metal.  Of course, these earrings can be expensive.  Hypo allergenic studs should be good, but I think there's a lot of variation and don't know precisely what that means regarding each particular earring.  I've seen some that claim "surgical steel' and while that should be good, again, I'm not sure what the standards are, even if there are any.\n\nGo with the gold, either yellow or white (if they like a silver look).  And make sure they're very clean when they change them (clean hands too).

Pounding on your workbench can put very high shock loads throughout.  In extreme cases shock waves can cause pieces of solid steel to separate (called spalling).  Further, as other answers mentioned, magnets tend to be brittle.  This is not because they are made of cheap iron.  Modern rare earth magnets are made using a complex sintering process where particles are compressed at slightly elevated temperature to hold them together.  They are notoriously brittle.  Finally, internal forces caused by the fields inside the magnet actually tend to force the magnet apart, splitting it from pole to pole.  Put this all together and poof - one magnet becomes several.

If I we're to guess:\nYou have tiny ammounts of iron in your bloodstream, the magents might attract the iron and pull the blood with it, and hence improving circulation. Although I may be wrong, my Dad has a magnentic bracelet, and he said it helps him a LOT.

There are some natural magnets. For example, the mineral magnetite is magnetic, and is found in lodestones. \n\nIf you have a magnet, you can stroke a piece of metal (not all metals, but some) and magnetize it; that is, turn it into a magnet. You line up the magnetic domains when you stroke it so it has a net magnetic field. If you put a radio reciever nearby tuned to the right frequency, you can hear the domains flip as you do this; this is called the Barkhausen effect. \n\nThere are also electromagnets. Passing an electric current through a coiled wire wrapped around the right kind of metal (called a shunt) produces a magnet. This is the kind of magnet one finds in MRI machines.

It is probably not really surgical steel, as it says, cheap metals make my piercings do this - I don't' know if it is really an infection or what, but I do know that if you have this green crud and you let a piercing heal shut it will leave a little green "dot" where the hole was.  I think I would clean it good with peroxide to get the crud to bubble out and then buy my jewelry at a piercing shop, only, not a cheap place in the mall, etc.

it's to do with the magnetic field of the water and or the geology. I did gold exploration for several years and on weekends we'd help the local farmers source underground water. And we used both a magnetometer to chec k for magnetic anonamalies amd then walked exactly the same path with a diving rod, a piece of fence wire and the rod would move at exactly the same places we found magnetic kicks with the magnetometer.

okay, I'm thinking "why do you people assume we might have metal in our EYES?!"\nbut ....\n\nBefore the test\nYou will need to remove all metal objects (such as hearing aids, dentures, jewelry, watches, and hairpins) from your body because these objects may be attracted to the powerful magnet used for the test. If you have had an accident or you work around metal and there is a possibility that you have metal fragments in your head, eyes, skin, or spine. X-rays may be taken before the MRI to confirm the presence of metal and to determine whether you can have the test.\n\nalso, it says to watch out for metallic tattoos.

I don't remember the ordering, but there's probably some metal out there that won't react?  Gold, maybe?  For regular metal, that sounds a bit iffy.

I think that metal detectors just work by setting up a magnetic field. When the apparatus move over a location that has a magnetic material a flux is produced that induces an electric current in the metal detector, activating a sensor.\n\nIf this is the case (i'm 95% sure it is), then the only factors affecting it's quaility would be within the machine itself as far the smallest current that activates the sensor.\n\nHeat and moisture would not change the magnetic field (moisture might theoretically alter the detectors magnetic field a little bit, but certainly not enough to measure). The both give the same result.

Gemstone quality crystals can be made into jewellery and so are vauable. Others are useful for their ores (hematite Fe2O3 iron ore, malachite copper ore etc.) I also heard somehing about using crystals for resonance but I'm not sure what that means lol hope this helps\n\nP.S. Quartz ie. silicon used for glass

Unlike Audio and Video Tapes, which are magnetic recordings, CDs and DVDs are optical recordings - and will not be affected by a magnet. \nBut, if the magnet has a rough surface which is in contact with the recorded side of the CD or DVD, then it can cause abrasions - which would affect their quality - but not 'ruin' them completely !

If you can measure the weight and volume of the ring, you could find its density.  The value will be different depending on what purity it is (24k will be denser than 12k, for example).  Most gold in jewelry is not 24k, but some alloy with nickel, copper, etc. that makes it harder.  These alloys are also how you get white, pink, and green gold.\n\nBiting a ring will only give you marks if it is 24k gold.\n\ndensity would be the easiest way, I'd say.  (density = mass/volume)\nYou'll need the equipment to measure pretty small masses and volumes, though, which most people don't have in their kitchens.
