Where do the extra particles go

In summary: The particles that do not hit the last detector have their kinetic energy measured in the X direction, which causes them to slightly change their direction towards or away from the observer. In the case of electrons, this results in a build-up of charge somewhere. For silver atoms, they would need to be scraped off the inside of the device after each run. It is possible to put particles through an X, Y, and Z direction by orienting the magnets in different directions. The particles are generated on the left side with their kinetic energy pointed in the Y direction, and the SG machine measures in the Z direction first, causing some particles to go up and some down. Then, the X direction is measured, causing half of the particles to move slightly towards

Web sites such as http://www.kcvs.ca/martin/phys/phys243/labs/sglab/stern_gerlach.html" explain the effect of a particle going through multiple SG detectors. For example:
sgsmall.gif


If electrons going in the y direction are first measured in the z direction, then the x direction and then again in the z direction, they fail to hit the detector.

Does anyone know what happens to the extra particles that do not hit the last detector? The site speaks of loss of "kinetic energy", but what happens to the particle? Do they simply stop and fall due to gravity? Do they take a hard right or left to miss the detector?

In the case of electrons, there must be substantial charge building up somewhere and in the case of silver atoms, do you scrape them off the insides of the device after each run?

How is it possible to put particles through an X, Y AND Z? If a Z magnet is oriented vertically then a Y is oriented horizontally and then an X is oriented along the path of travel... How would the particles "get in"?

Perhaps you want to link to the full-sized image, rather than the thumb.

Full size picture http://www.animatedphysics.com/sterngerlachmachine.gif" . The particle is generated on the left side and comes out with its kinetic energy directly pointed in the Y direction. The SG machine first measures the Z direction causing some particles to go up and some down by tiny amounts (in the mm). Of all the particles that go up, they measure in the X direction and sure enough, this causes half the particles to move slightly towards you and half the particles to move slightly away from you.

The weird thing is this: if you measure again in the Z direction, all the particles stop.

Gravity? No. Magnetic field, yes.
 

1. Where do the extra particles go in a chemical reaction?

In a chemical reaction, the extra particles are either used up in the reaction or are converted into new substances. The law of conservation of mass states that matter cannot be created or destroyed, so the total number of particles before and after the reaction must remain the same.

2. Do the extra particles disappear or are they transformed into something else?

The extra particles do not disappear, but are rather transformed into new substances. This is known as the law of conservation of mass, which states that matter cannot be created or destroyed.

3. Can the extra particles be observed after a chemical reaction?

It depends on the type of chemical reaction. In some cases, the extra particles may form a precipitate or gas that can be observed. In other cases, they may remain dissolved in the solution and cannot be seen with the naked eye. However, their presence can still be detected through various chemical and physical tests.

4. Why do some chemical reactions produce more extra particles than others?

The number of extra particles produced in a chemical reaction depends on the reactants and the type of reaction. Some reactions may produce more extra particles due to the nature of the reactants or the conditions under which the reaction takes place.

5. What happens to the extra particles in a closed system where no mass can enter or leave?

In a closed system, the extra particles will still be present, but may be in a different form. For example, if the reaction produces a gas, the extra particles may increase the pressure inside the closed system. However, the total number of particles will remain the same due to the law of conservation of mass.
