A graphic illustration of a right hand gently grasping a large arrow pointed diagonally upward. The thumb is up pointing in the same direction as the arrow. A smaller arrow underneath the hand indicates the direction to wrap the fingers around the large arrow. The title of the image is File:Right hand rule simple.png

me when I'm trying to remember the rotation of magnetic waves created by a current in a wire

Last time I checked a moving charge created a magnetic field, not a wave. And you determine the curl, not the rotation. You didn't remember

me when I'm trying not to let some nerd get under my skin because I struggled greatly with electromagnetics

I know right? you were literally responding to her meme in a complimentary way and she attacked you, lol. not sure what's going on with her lately. I think she's going through something. My trans sister has been in an AWFUL mood lately

I don't get it, GlizzyGuzzler, is something strange about this image? Should I get off on this post?

You don’t remember the ol’ twist n’ yank method from your EE days??

mossy_@lemmy.world · 6 pts · 2y (2 replies)

the only twisting and yanking I did was pulling the wires out of my breadboard when I was done with it!

You’re missing out, it gets hot and heavy under the optics bench after lab hours

I once used my left hand for the right hand rule because i was writing with my right hand during a physics test

Needless to say, i got the wrong sign

You may use the left hand, if you use the technical direction of current from '+' to '-'.

why even use the right hand rule when you can just take a random guess and be right half of the time

It is funny that this gestures are taught as some kind of mnemonics, but then some for some other application another mnemonic with the opposite hand and same gesture is introduced and I don't ever remember which hand was associated with what anymore. So I remember something about hands that doesn't get me anywhere.

I believe 3D graphics uses both to describe different coordinate systems (some are left handed and some are right)

Don't even get started with y-up vs z-up
