Can someone explain how the 3-finger rule applies to the magnetic

I mean... how much detail are you looking for? "Why" is pretty vague.

>>25621388
put the middle finger in your butt.you will start to understand after that

F = qv X B

Are you just trying to find out if /soc/ialites are less STEM than other threads?

>>25621388
If/when you get to more advanced physics, you will learn that it's due to your frame of reference relative to the current going through the wire. Minkowski geometries and Lorentz transformations are used to keep space-time constant. Come back after you've taken your special relativity and associated pre-req classes for that. At some point, you may throw your hands up in the air and realize that these are all wonderful math conventions that we've used to try to describe what we observe as humans in Newtonian physics.

Can someone give the basic jist of this shit please? I have a headache

What specifically are you having trouble grasping? You are dealing with vector math and crossproducts, electromagnetism, and wave-particle duality. It's not going to be as simple as mechanics.

The short of the long is each of these vectors are orthogonal (which you can verify taking their respective cross products). The right-hand-rule is a basic guide to help visualize which direction each of the othonormal vectors orient.

The choice is arbitrary, though, based on the historical choice that forces are "right-handed". There's no physical significance to the tool, other than a useful "mnemonic" of sorts.
