# Do magnetic fields lines have a motion?

## Recommended Posts

I did and experiment where I used a small circular cloud chamber to see the trail of mist created by an Alpha particle and I put a small cylindrical shaped rare earth magnet inside the chamber, the result was that every time an Alpha particle passed by the magnet the vapor trail left by it would be drawn toward the magnet and on some occasions the vapor molecules would find an orbit on the magnetic field of the magnet, I soon had a dozen or so molecules fallowing each other on a spiraling orbit from one end of the magnet to the other and then upon reaching the end just got flung off the orbit.

my theory is that magnetic fields have a motion from the negative to the positive which is why anything caught within the magnetic field is drawn to the magnet, and which is why quantum levitation is possible

No. Magnetic fields cannot correctly be thought of as moving. They can be thought ofhas hava direction though and given the Lorentx force acting on an alpha particle I would expect the results you just reported.

Where did you get a cloud chamber and source of alpha particles from if I may ask?

The force on a charge is given by F = qv X B. Since it's a cross product, the force is perpendicular to the velocity, which will give you circular (or spiral) motion.

Also, thinking of the way a cathode ray tube(crt) works with magnetic deflection, made me wonder about the charge on an alpha particle. Apparently it is positive which means you could use the principles operating in the crt except the deflection would be in the opposite direction (electrons having a negative charge).(IMO).

well it wasn't the Alpha particle that was spiraling it was the vapor cause by the Alpha particle shooting along a piece of black thick paper which was soaked in alcohol and then frozen by dry ice, the Alpha particle didn't seem to be effected too much by the magnet, the way I could tell was because the line of vapor went on a in a strait line even after passing the magnet, there was only a bend in the line caused from the pull of the magnetic field pulling on the vapor, and the vapor trail always resumed the strait line it was on before reaching the magnet, if there was a pull on the Alpha particle the magnetic field was too weak to cause vary much change in the particles direction and I was not able to see it with my naked eye.

I got the Alpha particles and cloud chamber together in a science kit from a place called Edmond Scientific, but the web site is www.scientificsonline.com there is also another place called The Chem Shop where you can get a bunch of Chemical stuff, its worth checking out if you don't already have a place to get all the Chems you would like

and also I think that the reason the vapor was more easily manipulated by the magnetic field is because the vapor has complete atoms which obviously have electrons which are as we know easily manipulated by magnetic fields, and from what I can understand would give any matter a stronger chance of being manipulated by a magnetic field as opposed to a Alpha particle which doesn't have any electrons

The alpha will ionize atoms as it passes by, so you might have been seeing effects from that, or it could be convection from having the dry ice (or possibly something else)

well its cool what ever the case, always thought I would need a special piece of equipment to see something like that

they do have a motion as i think .... what say ??????
