Magnetism and photographic imagery

[cliveh]

Could you employ magnets beneath the contact printing process of Cyanotypes to create special effects?

 

[Photo Engineer]

No. The Iron salts present are not magnetic!

[cliveh]

Iron is magnetic!

 

[E. von Hoegh]

Iron is magnetic!

The iron salts are not.

 

[cliveh]

The iron salts are not.

Oh, not even a little bit?

 

[tkamiya]

Only if you put some salt and pepper on it.

 

[Photo Engineer]

Not even a little bit and even with salt, pepper, oregano and basil! NOT MAGNETIC!

Some Stainless Steel is non-magnetic as well and it is basically iron!

Well this has been entertaining.

 

[cliveh]

So are we saying ferric ammonium oxalate has no magnetic properties?

 

[Oxleyroad]

Yes it has been interesting, and I could go on about how you can influence the magnetic characteristics of stainless steel, but it has absolutely nothing to do with making prints.

Why should it be about making prints?

I have a suggestion.

Go out and buy the biggest and strongest magnet you can and then try to drag some Ferric or Ferrous salt out of solution with it. If you do, then patent it and write it up for your Nobel Prize.

Curses. I was expecting something novel from this thread.

the heck with a rare earth or electro magnet
throw an electric charge through the cyanotype
while you print it and its subject and see if you can get a cyanokirilian print

What about a strong, alternating magnetic field such as that which might be generated by a rotating drum with magnets fixed to its surface in alternate N-S-N-S fashion?

You can use this technique to REPEL copper, aluminum and other non-ferromagnetic metals. It's the eddy currents which cause the repulsion.
This is how trash recycling machines separate ferromagnetic metals, non-ferromagnetic metals and paper/plastic/trash. First, they use a magnet to suck up the steel and iron. Then they use a rotating drum magnet to repel the copper, aluminum, etc. into a chute.

Would this technique work in our case?

Not even a little bit and even with salt, pepper, oregano and basil! NOT MAGNETIC!

But if you add some imported Parmesan Cheese, viola! It sticks to a magnet!

 

[Photo Engineer]

NO Tk. I tried it with a vintage Parmegiano Reggiano and it did not work! Sorry.

I am working on a Molle to see if it will work!

It is important not to confuse atoms with ions. Their magnetic properties are very different.

There are three types of magnetic susceptability; paramagnetism, diamagnetism, and ferromagnetism. The first two are extremely small and need special equipment to be measured. Most materials exhibit either paramagnetism or diamagnetism. A very few substances like iron exhibit ferromagnetism.

Nickel is magnetic, and nickel isn't iron.

Can light or radiation have an effect on ferromagnetism, to a degree that it could be utilized in some fashion to make an image? I'm kind of thinking along the lines of Xerox; where a charged plate of selenium loses that charge with light exposure. Any kind of similar phenomenon we can exploit with magnetism?

Curie effect.

Never said that it wasn't.

In fact, the AlNiCo magnet was one of the strongest until recent advances in materials science passed it up. I don't know what the leader is now.

Under very high magnetic force, it has been demonstrated that most objects are magnetic. In fact, a recent demo on TV showed a spider suspended in a chamber, in mid air, by a huge magnetic field.

The electromagnetic forces allow electrons to create magnetic fields and magnetic fields create electricity. This has been known for hundreds of years, and was demonstrated by Benjamin Franklin among others. These fields can influence radiation, but they cannot influence light. Gravity can influence light, but there is no electrogravitic force or magnetogravitic force (as once was thought) that can combine all 3 forces and allow control over light, magnetiism and electricity.

Faraday Effect

Put "Faraday Effect" into Wikipedia, and go from there.
It's been known almost as long as photography.
Not the easiest way to modulate an image, I think ...

Nickel is magnetic, and nickel isn't iron.

And cobalt.

These fields can influence radiation, but they cannot influence light. PE

But can they influence chemical reaction?
