Right hand suggestion (lemmy.blahaj.zone)

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

Those curved sin waves...

If you know what I mean 😉

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 points 1 week ago

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 suppose they would turn the air conditioning off when everyone leaves...

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

[-] Successful_Try543@feddit.org 7 points 2 weeks ago

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

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)

[-] s_s@lemm.ee 5 points 1 week ago

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

[-] affiliate@lemmy.world 19 points 2 weeks ago

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

[-] HEXN3T@lemmy.blahaj.zone 8 points 2 weeks ago

I have to admit that title is really clever

The ol' twist and yank method

[-] SzethFriendOfNimi@lemmy.world 6 points 2 weeks ago

Who would ever use this?

Atomic spin and chemical bonds have entered the chat

[-] Successful_Try543@feddit.org 5 points 2 weeks ago

Or angular momentum.

Haha, a reference to Hitchhiker’s Guide to the Galaxy!

[-] jabathekek@sopuli.xyz 4 points 2 weeks ago

...torsion.

No thanks. I prefer the 3 variable left hand rule.
