There are more articles on this, but is this not akin to turning a magnet on and off and would this not be easily made into a magnetic motor? If you can increase a magnets strength to 150% and then decrease it to 60% with just shining a certain color of light on it, this is similar to turning a magnet on and off. Comments please.
1.5 times more magnetic than what? There is no words on the flux levels or efficiency of the magnetic field controlled by light.
You miss the point that you need strong flux levels to make a motor capable of delivering high torque at an usuable RPM range to achive any useful output.
This "light magnetic device" is inteded to digital storage, not motors. But the thought was good anyway.

The new plastic magnet becomes 1.5 times more magnetic when blue light shines on it. Green light partially reverses the effect.
I understand that the device was meant for digital storage, but if you can increase a magnets baseline capability by 150% and then reduce it to 60%, that is similar to turning it on and off such as with the radus boots. If you can increase/decrease the strength of the magnetic field, it shold be easy to make a mechanical process using the magnets.
But there is no word on how efficient the on/off mechanism is!!!!
If it takes more power going into the light than what is generated in magnetism by the light, you just have a regular under-unity system.
The magnetism must be created many times more efficently than ordinary electromagnetism to create an overunity motor by this methode.
Well with this material we can build a rotating generator that get it's energy from the sun. But only if the magnetism cuts instantly as the light goes out.
You only need a little piece of this material to build a small motor.
This is interesting, could be the key for free energy!
Look Honk, you talk about efficiency and other parameter we all know are needed to achieve high performance motors, but think only in a "magnetic stick" as a rotor, and you have only 2 magnets on the sides 1 N facing the stick and 1 S facing the stik. You only need to change the polarity of the stick to make it move. If the magnetic field changes only by light...
I'll bet almost anything that a regular solar cell is many times more efficient than this "mag-light"

I am sure you could use this to make some king of rotary device, but I was thinking more on the lines of a pump. You put a weight on the bottom of a piston that weighs the same as the lifting power of the 60% reduction in force to pull down the piston and then when the green light force of 150% is applied, it would pull up the piston.
Honk, dude, investigations on magneto optical components are based on the teory of being more efficent and faster than traditional electromagnetism ;)
I doubt more efficient, but most probably faster and easier to miniaturise to fit inside a chip or harddrive.
This is a amazing break through. This could be used for what all of us magnet motor over unity searchers have been looking for.
If the blue light creates a draw and then the green light reverses the effect by 60%, it would only require a 40% placement difference with in to two distances from the magnets to get rid of the draw back effect.
I see this as a amazing opportunity for us provided we could get our hands on the technology.
Good luck trying to build a motor if you ever get hold of this stuff. I'll cheer on your....
But I'll bet the flux levels are extremely small (like in a harddrive) and the energy output from
these small light induced magnetic fields is much lesser than the power required by the light source.
It's simply not enough to flip a field, it also have to be strong enough to perform some real work.
I'm talking of an usuable RPM range at some real torque. Just having speed is useless.

We can make an enclosure with holes on the right place, put some color filters on holes and set the thing on sun...
OK, go for it.
But try to find the flux level being created before planning a design.....
You can't use microteslas.......
G'day all,
Has it occurred to any of you guys that this kind of technology can only work on a very thin film. How would you get the light into a block of any thickness beyond a few microns to cause a reaction?
For data storage and so forth, quite feasible. Anything more solid, I don't think so.
Hans von Lieven
Yes, the thickness issue did occur to me, but I did not think it would need to be that thin. Here is another article that expains it more. The other article is slightly misleading.

It appears that the light causes the magnetic material to align differently which increases or decreases the strength.
After reading this new article we can call this a dead end solution to OU machines.
The energy going into the "light sensitive magnetism" is in the order of many thousands or millions times higher than the magnetic output.
This is a pure data storage technique at very low and rapid flux levels. Leave it at that. This idea is dead.
Ok... but what was interesting, was that you can control a magnetic field (no matter how strong or efficiently) with light. Did you know it to be possible in the past?
@scorpile, I think the thing with this is is that it is not really controling the magnet itself, but causing the magnetic particles imbeded in the plastic to align or misalign.
And sounds logic to you?
"And sounds logic to you?"
Not sure what you are inferring to.
If you mean the aligning, that is what it says it is doing in the last article I posted. Please read that if you have not.
