  1. sorry I put it on the wrong forum before if you have any two gases in different containers that are same size at the same pressure and temperature, what is true about the moles of each gas i got it how do I delete a topic anyway?
  2. I'm sorry but I'm not sure what you're saying. Maby I had visualize the magnetic field of an electron wrong. So to make sure if I'm on the right track where is the north and south pole on a moving current?
  3. Are there any useful(or great) websites that teaches you how to use breadboard or shows you the different applications you can apply to a breadboard? (i am not sure if this post belong to this forum, but out of all the other one-this one just seems more suitable.)
  4. let just say I had a moving magnetic field close to the circulating ions, will that helps the moving ions to gain back the energy they lost?
  5. How to calculate the motion of ions in a magnetic field ?
  6. I had heard that a common solar panel has about 20 to 30 percent efficiency. The reason was, as I had heard, the electrons only consume the visible part of the electromagnetic spectrum and reflect the rest of the light waves. But why is that so?
  7. An accerlerating free charge radiates light, thus loses energy? Is there an explanation for that phenomenon ? ( why it happens)
  8. Quite not though. I remember in that thread all the posts were about how magnetic field couldn't increase the speed of the negatively charged ions and how the field can alter the path of the ions. But what if I used a particle shooter that shoots particle individually, won't that eases the possibility of collisions.
  9. Ok well I have 2 coils around the iron bar, making it two battery and two capacitor. As the first capacitor charges up, the second capacitor will release the charged energy; and as the second capacitor charges up, the first capacitor will release its energy. And the two battery will release two different voltages- high and low. So as the wires combine, it will make a pattern like this--high, low, high, low- and so on. I was thinking that if that will produce an iron bar with changing magnetic field, thus can also produce electricity when a wire is wrapped around it.
  10. I might be my lack of interpretation because I don't know what you're saying, I think we're viewing two different picture there.
  11. as the capacitor from the first coil charges up, the current from the second coil will start to flow; as the capacitor from the second coil charges up, the current from the first coil will start to flow The field will only decrease as the batteries begin to drain out right? I don't understand what you mean by the field will decrease exponentially over time and so will the current, as the capacitor charges up
  12. if I wrapped a coil around an iron bar, put a capacitor and a battery on the wire and also do the same with the second coil that I also wrapped around. The only difference is that the voltage that will be produced from one coil is higher than the other coil and the capacitor is there to make sure the moving electrons from the first coil won't intervene with the moving electrons from the second coil. Will that also create a moving magnetic field? Sorry if it is hard to visualize by the way it was written there, tell me and I will try to word it in a different way.
  13. if I want to visualize the magnetic field of a moving electron, can I say that it is the same as pushing a stick magnet (horizontally) across?
  14. the magnetic field of a magnet forms two half spiral that comes out from the N to the S but an electron's was a spiral that warps around itself, Why are there field lines different? Shouldn't they be the same since a magnet's field lines is basically made of electrons facing the same way?
  15. I had been thinking lately about why moving magnet perpendicular to a wire causes electric current. my conclusion is that the changes in magnetic strength ignites the electrons to move since a magnet's strongest field comes from its N point and basically what a moving magnet is doing is changing its field strength. Please help me out if my logic is wrong since I haven't been taking physic since junior high
  16. i thought that if the individual electrons in a current had its own magnetic moment, shouldn't negatively charged particles be also possess that property ?
  17. Timo, can you tell me the basic knowledge/approach on how to calculate the motion of ions in magnetic field?
  18. Thank you Timo/TonyMcC Those comments were very helpful
  19. Sorry for the misunderstanding. What I mean is the potential differences pertaining to electricity is often compared with water falling downhill What my question is, is why do you need a complete circuit to get a voltage reading on a volt meter. Shouldn't the electrons start flowing once it's connected to the terminal that the electrons is oxidized.
  20. I always have difficulty accepting the analogy between the flowing of electrons because of potential differences and water flowing downhill. The reason is shouldn't electrons begins to flow once the wire is connected to it? Why does it needs a complete circuit? This is a very general question, and I hope someone could get my thinking in the right direction.
  21. One more question When the ions is effected by the magnetic field, it will be traveling along the imaginary magnetic field line right? When it travels along the imaginary magnetic field line its speed will not increase or decrease but stay at a constant velocity right? Also, does having a stronger magnetic field means having a bigger magnetic field line? Please correct me if my reasoning is wrong. Thanks.
  22. Timo, Thank you for the help. But can you tell me what the letters stand for?
