Is platinum magnetic?

Maybe when use the word magnetic and magnetism it's not so helpful in this context, because we all get mental images of compasses and magnets picking things up.

Magnetism is not my strongest area, I'm better with electricity and gravity, but they all work in very similar ways. If you think of electricity, I'm sure you would remember being taught early on that there are 'conductors' and 'insulators', then when you learn at a more advanced level that is chucked out as you learn the conductivity of materials is something much more varied than that. Almost anything will conduct electricity, just some things do it incredibly badly.

I understand magnetic theory is pretty much the same.

The stuff at the bottom of this link explains nicely what is behind magnetic properties.

There is a good page here on calculating the magnetic susceptability of various materials.

In other words, in answer to Eos' question, everything has a magnetic susceptibility, it just is negligible for most things. So you can take those magnets out of your shoes now.
 
In other words: No, Kumar. Sorry, but you cannot assume that homeopathic drugs somehow stores something magnetically.;)

Hello Mr.Hans,

If all substances are magnetic, we can think so. But I am not able to understand its logic as bit technical. I am just thinking that as magnetic effects is transfered into iron peice or just by rubbing--why it could not be possible in other substances if those are also somewhat magnetic. More harsh rubbing as in potentization process may mean something.:)

Well you could speculate, but you are looking to find a theory to prove a phenomenon for which no evidence exists.

I can tell the difference between a magnetised bit of iron and an unmagnetised one. It might be possible, with equipment sensitive enough, to tell if a something fairly unsusceptible like wood has had prolonged exposure to a strong magnetic field, I don't know. It wouldn't be possible with a fluid.

There is no way to tell the difference between a bit of water and a succussed remedy because there is no difference. When you've found a way of telling the difference with any statistical reliability then we can talk about theories as to what's going on.

Did you forget the Hanneman quote I gave you already?
 
Benguin,

Thanks for information. You want to say that their may not be any measurable effects in most of other substances than iron( cobalt).

Btw, which substances can interfere MRI imaging?

Did you forget the Hanneman quote I gave you already?

But who agrees here, with Dr. Hanneman's other quotes? If you all would had agreed, it would have saved lot of time & energy to me & others. :)
 
Sorry, I got details of banned items on MRI here. But I want to know that if MRI based images of body parts are due to the presence of iron in body parts or it takes imaging effeced by other body substances also?? I want to know the basis of target parts for taking their images?

No, because that is one of the special things with iron and a few other metals: They can be magnetized, and retain a magnet field. Other substances (like water, alcohol, and lactose) cannot retain a magnet field.

There are several more holes in the thesis, but this is really enough to dismiss it.

Very interesting article, thank you! Apart from explaining how MRI scans work in a very understandable way, it indirectly delivers another ground shot to Kumar's newest thesis: Since you can place a human in a 2 tesla magnet field :eek: without appreciable side effects, it is evident that in the unlikely event that some kind of magnetic effect exists in hom. remedies, there is not a snowball's chance in heII that some infinitesimal effect could have any influence on the body.

It is also a bit of a slap in the face of other magnet therapies.

Well aside from the material issues, I can't see how it is possible for a magnetic field to be created in a fluid, I'm not sure what you'd get if you could create a fluid of pulverised magnetic iron, but I'd be surprised if it would be anything.

Can I just point out, in case I confused anyone with talking about magnetic properties of all materials, that magnet therapy is utter steaming gonads that makes me laugh like a hyena.

Kummy-wummy ... the molecules in a fluid are moving about constantly, even in an apparently static fluid. Magnetic alignment can only occur for a transient moment before it will disappear through random rearrangment of the molecules in the fluid.

In any case, any effect as remote and weak as would occur through succussing two non-susceptible materials (water, duck's liver) is likely to be overridden by the earth's magnetic fields.

There is nothing latent to be seen ... here, an experiment for you;
1. Take two pieces of iron
2. magnetise one
3. Melt them both
4. Allow them both to solidify
5. Find a way to tell which is which by analysing their different magnetic properties.
6. Phone Randi up and collect your million.

Try not to burn yourself, or set fire to anything. I'd feel guilty.
 
I remember hearing a risk like if you got metal bits in your eyes or something, and went into an MRI, the magnet could move the metal and cut your nerves and blind you. They do an X-ray of your eye.

Does this X-ray include your whole head, or just your eyes?

'Cause I was exposed to a whole lot of dust, some got into my ears even. What would happen then?

It's if you're likely to have been exposed to airborne iron filings and such like. The medline link Kumar gave covers it well.

Surely, the weaker the field, the stronger the effect

Probably get a massive aneurism, your head would explode, and somebody would have to hose out the MRI machine.

At the risk of being highly pedantic, as I understand it electricity and magnetism work in the same way, gravity works differently...
 
I wear my platinum wedding ring into the MRI scanner room every day and I havent noticed any force being pulled on it. I dont know how pure the ring is, but if theres any impurities in it, they are not of sufficient magnitude to produce a noticeable force in a standard 1.5T field.

Welders and other people who work with metal cutting can accumulate very small particles of iron or other ferromagnetic metals into their eyes. If put into an MRI machine, they may be able to feel heat or pain in their eyes, so of course you are supposed to exclude anybody who fits this profile from getting a scan.

Some older tattoos used iron in the mettalic inks which could cause skin burns. However, most of the tattoos of the last 20 years or so use iron-free inks, so if its a recent tattoo the chances are greater of having no complications. We use a voice monitor to make sure that there is no local RF heating for people with tattoos, and if there is, we immediately cancel the scan. We've never had any serious burns with tattooed patients, just some minor pain that subsided immediately after leaving the scanner room.

Kumar,

MRI has NOTHING to do with imaging iron. Conventional MR scanning is based on hydrogen, not iron. MR spectroscopy uses other species such as sodium for example, but iron is not one of them.

Don, Interesting site in easy language thanks. It appears by understanding this site that when this much magnetic effect can not effect then other possibily can not be possible. But, this is the only mystry of homeopathy & TRS alike how a needle can effect when a sword can not effect. We may continue accordingly.

The above post should win some kind of award somewhere.

No, not the language award.

Possibly, the anti-language award.

No, we may continue accordingly when we have some evidence that homoeopathy and TRS do effect.

Oh, that was "mass existing belief", not to be denied.

Sorry, not going back into that revolving door again thank you.
