Magnets + Lasers?

[nikokapo]

i was wondering if any magnet (rare earth neodymium or something stronger) would have an effect on a laser beam/dot (not the circuitry or the laser itself),

will it?

Danke

 

[thejunkmonger]

as far as I understand no effect at all and i've been trying but no bending in my beam

 

[thejunkmonger]

magnets ? did someone say magnets?

 

[nikokapo]

oh boy, what do you have there!!!!!

and to think i ordered 40 8mm dx magnets ....maybe i should start building a tesla coil and a super electromagnet

You would need an unimaginably strong gravitational field in order to "bend" light. I think

This looks like a question for wannaburn or likewhat I think I recall reading someones post about using magnets to screw up the ~3000nm line in a red HeNe to make the 632nm line more powerful since the IR line was interfering with the red one or something :-/ I'm sure someone could give a better explanation.

I don't think you need an "unimaginably" strong gravitational field though.The Sun's field is strong enough to slightly bend light.I also just think

 

[nikokapo]

why?

[*climbak jumps in and gives an awesome answer*]

Back in the day when I knew nothing about lasers I used to take a leadlight and hold some N48 Cubes up to it, and to my surprise no light bending occurred ;D

LOL magnets of course I have everything that's why i'm called the junk monger. Also am starting to build a van de graff machine already started making the bowl for up top.

good lord Chuck..

will you build a hand-powered one (mechanical)?



i dont remember the name, but when i went to USA (Cleveland, OH) i was taken to the science museum, and there was this huge IDK-if-it-was-a-van-de-graff machine but when you touched it, static electricity made your hair spike like hell

am i wrong?

 

[Hemlock_Mike]

Strong magnets are often used in high powered gas lasers laike HeNe to control the plasma arc in the tube. You did bend the beam but not enough to detect.

Well, since plasma is just charged gas, and charges form magnetic fields when induced by magnets, then that's why you can control a plasma arc with magnets.

But changing light with magnets? I don't think that's possible. I know gravity fields will work, but not magnets...

 

[nikokapo]

doesnt a CRT use magnets to straighten the beam?

 

[bobobob121]

lets just say it would have to be the same magnetic force as the sun. but by the time you used it you would drown to death because all of the water on earth would be pulled to your location ;D

 

[nikokapo]

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

i'm a learning thirsty bas**rd

If magnets would bend laser light, then just looking at the magnet you would see distortion around the corners like it was the nevada desert.

Compare it to the 'flat' reflections of building winows. They're flat, right? Then why do they look so distorted when you look at them from a great distance (for example, from the highway, looking at a building 100 meter away). Very small angle distortions multiply with distance.
