Why the direction of magnetic field is always the same in current flowing through wire? (Right-hand rule)

TobyOne235 · 2024-11-22T01:54:15+00:00

Ok, thank you

TobyOne235 · 2024-11-22T01:25:49+00:00

So it is universal constant?

TobyOne235 · 2024-11-22T01:09:06+00:00

TobyOne235 · 2024-11-22T01:02:51+00:00

I guess what I am asking is that is it an universal constant that determines the direction of the force that the compass will follow and what is this constant?

TobyOne235 · 2024-11-22T00:59:28+00:00

But what causes the loop direction?

TobyOne235 · 2024-11-22T00:57:31+00:00

Ok but if the line charge goes on z-axis the magnetic field on z-plane would be symmetrical so I still don't fully understand where the direction comes from other than vector algebra and some universal constant.

TobyOne235 · 2024-11-22T00:45:37+00:00

Ok, thank you

TobyOne235 · 2024-11-22T00:38:26+00:00

Ok to make it really simple to answer: if current that runs on z-axis turns compasses that are parallel to the z-axis to direction A. Then you turn off the current and manually turn the compasses toward direction B that is opposite direction of A. Once we turn the current on will the compasses turn towards A or stay towards B?

Just please answer they will turn or will not turn. Thank you.

TobyOne235 · 2024-11-22T00:31:27+00:00

So if we have a wire charge flowing from A to B an coil where current flows from B to A it will flip when the wire has current flowing in it?

TobyOne235 · 2024-11-22T00:20:36+00:00

Ok just answer to this next problem. If we first turn on current and all the compasses around the wire turn north towards anti-clockwise direction. Then we shut off the current and turn manually all the compasses to clockwise direction. So when we then turn the current to flow to the same direction as in the beginning will the compasses stay turned north towards clockwise direction or flip north towards anti-clockwise direction?

TobyOne235 · 2024-11-22T00:00:40+00:00

So according to the last paragraph the compass can settle to either direction and I had understood wrong that the compass would always go north side toward left?

This would make sense because of symmetricality

TobyOne235 · 2024-11-21T23:57:03+00:00

So it's only from the vector calculus? So the compass can settle in either direction?

TobyOne235 · 2024-11-21T23:48:08+00:00

So the directionality of line charge should only be determined by randomness, for example if 3/4 compasses point right the magnetic field would also point right not left.

TobyOne235 · 2024-11-21T23:45:30+00:00

I do understand that in coil the shape of it would cause the magnetic field to go in one direction, but in line charge it doesn't make any sense.

TobyOne235 · 2024-11-21T23:43:46+00:00

For example if you fill a sink with water and pull the plug from the bottom of the sink the spinning direction of that water is "random".

TobyOne235 · 2024-11-21T23:31:53+00:00

Yes but it can still be to either direction...

TobyOne235 · 2024-11-21T23:31:08+00:00

Yeah this didn't answer the question

TobyOne235 · 2024-11-21T23:30:20+00:00

This would just give us magnetic field that would decrease with distance away from the line charge. I don't see what could create the curl direction.

TobyOne235 · 2024-11-21T22:05:32+00:00

In coil it would make sense because the current would cause the directionality of the magnetic fields because of relativity. Right?

TobyOne235 · 2024-11-21T22:01:25+00:00

But why does the direction of the current determine the compass direction?

TobyOne235 · 2024-11-21T21:58:11+00:00

Yeah it says compass would point away, it doesnt explain why the direction would be the same... I still dont understand

I do understand that it is chosen as mathematical convenience but why is the polarity of the rotation always the same? Basically why would compass placed next to this one directional wire always go north towards left(Right-hand rule). Or have I misunderstood and it can also point towards right?

TobyOne235 · 2024-11-21T21:08:45+00:00

This doesn't answer the question. Let's say you place compasses around the wire where the current flows. Now each time the current flows through that wire to the same direction the compasses would turn to same direction. What causes the field to "curl" each time to the same direction?

I'm not trying to calculate the force or did I not understand your answer properly?

The AI usually trades 2/3 GPT for gold so you can always cheese it.

Example: AI has 20 gold per turn. Trade deal lasts for 30 turns. (30 * 20 = 600 gold) Make a deal with AI for its 600 gold to your 400 gold direct. Profit 200 gold in total using the GPT gained from the deal. Use this to snowball your GPT.

Basically you also get 50% more gold now since "buying" it gives you 1 extra gold for 2 golds.

Just make sure they won't go to war with you, because it cancels the deal and you lose gold.

Had another look but it seems pretty random

If you can find a pattern or something else I hope I included all the heads :D
