wj25czxj47bu6q (A) | aaaaa I can't think anymore | 01:21:23 |
wj25czxj47bu6q (A) | My physics is too rusty | 01:21:32 |
idkrn | In reply to @wj25czxj47bu6q:arcticfoxes.net Magnetic force is a function of radial distance A radius is 1d btw | 01:22:05 |
idkrn | The magnet will not pull something in a circle | 01:22:43 |
wj25czxj47bu6q (A) | In reply to @idkrn:envs.net A radius is 1d btw Technically yes, but it's a 3-dimensional vector | 01:23:08 |
idkrn | Ok but it could also be a 5d vector if the rest of the vector was 0s | 01:23:46 |
idkrn | It's just a line | 01:23:56 |
idkrn | A line can exist in any space | 01:24:05 |
idkrn | That doesn't change how many dimensions it has | 01:24:13 |
wj25czxj47bu6q (A) | It's a 3-dimensional vector in this context because our world is 3-dimensional | 01:24:23 |
wj25czxj47bu6q (A) | You can move your body in 3 dimensions | 01:24:36 |
idkrn | In reply to @wj25czxj47bu6q:arcticfoxes.net It's a 3-dimensional vector in this context because our world is 3-dimensional The force still acts between 2 points | 01:24:48 |
wj25czxj47bu6q (A) | In reply to @idkrn:envs.net The force still acts between 2 points Yes, the quantity that matters is the length of the radius vector | 01:25:10 |
wj25czxj47bu6q (A) | In reply to @idkrn:envs.net The force still acts between 2 points * Yes, the quantity that matters is the magnitude of the radius vector | 01:25:17 |
wj25czxj47bu6q (A) | * Yes, the quantity that matters is the magnitude (length) of the radius vector | 01:25:33 |
idkrn | The vector field is a bunch of 1d vectors plotted | 01:25:46 |
idkrn | They're all still 1d vectors | 01:25:53 |
idkrn | It doesn't matter how many dimensions it passes through | 01:26:06 |
wj25czxj47bu6q (A) | The magnetic field is a 3D vector field | 01:26:12 |
idkrn | A line is always 1 dimensional | 01:26:13 |
wj25czxj47bu6q (A) | Redacted or Malformed Event | 01:26:36 |
idkrn | What | 01:27:11 |
Krzysztof | MSPaint to the rescue... | 01:27:28 |
Krzysztof |  Download magnets.png | 01:27:34 |
Krzysztof | this will still mostly work | 01:27:48 |
Krzysztof | magnets are doing most of the work here | 01:27:52 |
Krzysztof | friction helps, but not much | 01:27:55 |
Krzysztof | I'm still pretty sure I'm right | 01:28:16 |
Krzysztof | The lateral force slides the magnets apart... magnets don't like being apart
hence
magnets (mostly) stop the wallet from sliding laterally | 01:29:09 |
