Magnets + Lasers?

[Benm]

you can use magnetism to attract H[sub]2[/sub]O???

Attract isnt really the word of choice here, but magnetic fields can deform water to some degree. This can be demonstrated using a dish of water set over a very strong magnet, but even then the effect is very difficult to observe. Another way to demonstrate is by moving a strong magnet over a very stable water surface, which actually pushes the water out of the way. Someone coined the term 'moses' effect for that behaviour.

What about the 4th state of matter?  Scientist conclude plasma to be the 4th, when it is actually only gas reacting with energy, or electricity.  Magnets alone are crazy. I was reading this http://en.wikipedia.org/wiki/Magnet the other day, really interesting information.  Technically light is not considered a state of matter, however I personally believe that energy (mainly electricity) in general should be considered a state of matter, (or a state of existence) because they have properties, can be experimented with, manipulated and controlled, just like solids, gasses, and liquids.  Same with light, (DPSS lasers for example; combining light radiation (photonic energy) with solids creating a reaction).  I believe that energy alone should be the 4th state of matter, along with plasma.  A functioning magnet contains an electric charge.  And so back to Nikokapo’s question, (and not a stupid one if you ask me) I believe that it is possible for magnets to have some sort of influence on light, or lasers.  Similar to how a plasma screen works, perhaps this could be how 3d holograms will be made. Or maybe light sabers!  But there might be the need for other materials as well like gas, liquids, other solids, or super amounts of energy!  

Just some thoughts.

I dont like saying that photons have mass. They contain some energy which can be said to have mass equivalence but they dont really have mass, you are just confusing people. Photons do carry momentum of h/lambda, since they have momentum you can have radiation pressure from light, but dont say that they have mass because people think of mass as something they can hold in their hand and throw up and down so they can feel it.

mass is something that exists and has shape it doesnt have to be a 20ton elephant to know it's there. indeed, electrons, neutrons and protons have mass and they're "untouchable"


there are some nice answers here..

Benm, are you saying that the magnet itself as an object can bend light instead of magnetism?

in addition, if magnets can have an effect on H[sub]2[/sub]O then if somebody lived under a very strong magnet then wouldnt he have growing problems or cancer?

 

[Ace82]

So you can't feel the burn of a powerful laser? Light isn't used to cut solid material? I also believe that light doesn't have mass, (you can't weigh it on a scale) either is electricity. In regards to magnets, the connection between light may not be exactly "physical" or massive, but electric. Anyway, electricity is still a phenomenon. http://en.wikipedia.org/wiki/Electricity :

Does Light have mass?

"That depends on which of two definitions of ’mass’ a particular physicist likes to use, and what type of light you’re talking about.

One definition of mass says that anything which has some gravitational pull on other objects has mass. By that definition, light has mass. This definition of mass is the same as the definition you get if you ask what ’m’ you have to multiply the velocity ’v’ by to get the ’momentum’ of an object. Momentum is a measure of how much stuff is moving which way. When things bump into each other, the total momentum doesn’t change even though it might be traded between the objects. Think of when two balls bounce off each other. Light has momentum, which means we can actually measure the push it gives to objects it runs into. This is the definition used by Einstein, for example in the famous equation E=mc^2.

On the other hand, physicists often find it convenient to think of mass as something that doesn’t depend on how an object is moving, also sometimes called the ’rest mass’. They call the mass of some object the mass that it would have according to somebody who says the object isn’t moving. Light always is moving, so by this definition (or more careful versions of it) a light ray has no mass.

Switching between those definitions can lead to a lot of confusion."


They say when you die, your body looses 28 grams.

Benm, are you saying that the magnet itself as an object can bend light instead of magnetism?

Yes. Provided you could make a really big magnet, you would observe it bending light. Of course it would have to be as big as the sun to do the textbook observations, but it would not matter if it were magnetized or not.

in addition, if magnets can have an effect on H[sub]2[/sub]O then if somebody lived under a very strong magnet then wouldnt he have growing problems or cancer?

I dont know about growing problems or cancer, but i can imagine it could have an effect. Short duration exposure to extremely large static fields has been proven harmless (you can lay down in an MRI scanner all day and be perfectly fine).

As far as i know little has been done to test lifelong exposure to multi-tesla fields in animals, but i guess that would be useless. We all grow up in the earths magnetic field with no ill effect, and very large fields would be something people arent accidently exposed to - imagine living in a house where every piece of ferrometal would shoot up to the ceiling or either wall... you'd go mentally ill, perhaps

i never understood that, why does that happen?

------------

ok, now.

let's say light has mass and you want to cut a piece of metal with strong light

then you would apply the light to the metal, assuming that the mass particles from the light source will travel to the metal and colliding with it, creating friction and thus melting the material eventually, creating the effect of "cutting" through the metal.

friction would result by exciting the metallic molecules so you can state that light has to have mass to produce the effect of "heat" onto metal?


(i'm trying to figure this out..i'm not saying things really happen like that)

[edit]edit: one more Q, why is Tesla presented in such small numbers? (yes, small is relative..)[/edit]

They say you loose 21 (not 28, sorry) grams when you die because that is the mass of your soul, your energy life force. Once you die, it returns to the source.

what if i dont believe in souls and i want a real justified explanation?

 Well, there are many things with no satisfactory justified logical explanation (like electricity).  Why else would a body instantly lose 21 grams from dieing?  And it's 21 grams for anybody, a baby or a 300lb adult.  But I'll try anyway....

Where does electricity come from?  I believe that there is another dimension or plane, of which all life, light, energy, electricity exist running parallel to all existence in the universe.  Like a tree, has roots, then a trunk, then branches.  Energy would be the trunk, the point where all collimates, under the ground roots spreads to thousands of different areas and same with the branches.  We have infinite ways of pulling electricity from the invisible plane and convert it to what ever we please, even store it.  So when we are alive, we are connected to the energy plane through the need to have energy to live, as if we are plugged into a power supply.  Well that's when food/ water can object, but this is a different type of energy.  Magnets have a different type of electricity then that needed to supply power.  So our "soul" would be like the magnet's charge, returning (yeilding, as positive - birth, or negitive - death) back to the earth, or like a "dead battery" has no more energy, returns to the energy plane.  

This is only my theory, and I have no proof of it.  This is a poor short explanation of it too, but I'm only sharing thought.  

 

[roSSco]

There is an explanation. It's BS! Look into it. It has been proven to NOT be fact.

Ok, this topic is done,moderator move it to the philosophy forum.

lol I was waiting for that. Another of my beliefs is to keep an open mind. Therefore, it is only a conception, and has not been concluded definite until I personally see a person die on a scale. And a man DID walk on the moon.

dont bash our thread!!

we are discussing STUFF!


ace, i still dont believe (i am sharing opinions also) in the fact that there is something "material" (if we adjust energy to have mass) that "lives" inside our bodies and escapes when we die, just because if it's energy then it doesn't have knowledge to know how to return to that source you say.
my justification would be that you cannot CREATE energy, just transform it. so for every child born you should then create the soul/energy for that newborn child.
if you say that the mother transfers that energy to "create the new soul"....then: there are no studies of a mother losing X grams for the transferred energy (if it had weight).
how can it escape the body and retain shape? (or not) dunno...but i still dont believe in it..


life exists because of the mighty Friction!
if there was no friction, nothing could exist. (p <--> q !!)



and again: why is Tesla presented in such small numbers? (yes, small is relative..)
