The Right Hand Rule: it's not just for electrodynamics anymore.

Click For Summary

Discussion Overview

The discussion revolves around the application of the right hand rule beyond traditional contexts, exploring its practical uses in everyday tasks and its implications for left-handed individuals. Participants touch on various scenarios where the right hand rule may apply, as well as alternative perspectives for left-handed users.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants suggest that the right hand rule can be applied in practical situations, such as screwing in a light bulb or capping a jug of milk.
  • Others humorously propose that the right hand rule has applications in personal contexts, indicating its versatility.
  • A participant raises the issue of left-handed individuals, questioning whether they are at a disadvantage in using the right hand rule.
  • Another left-handed participant claims that they can simultaneously apply the right hand rule while writing with their left hand during exams, suggesting an advantage.
  • One participant introduces the idea that the left-hand screw rule may be more effective in the southern hemisphere due to Coriolis effects, while proposing that left-handed individuals in the northern hemisphere might benefit from Fleming's rule.
  • A later reply mentions modern neuroprosthetics as a means for left-handed individuals to adapt to right-handed conventions.
  • Another participant connects the right hand rule to the concept of the cross product and unit vectors, suggesting its relevance to torque applications.

Areas of Agreement / Disagreement

The discussion features multiple competing views regarding the applicability of the right hand rule and its implications for left-handed individuals, indicating that no consensus has been reached.

Contextual Notes

Participants express varying assumptions about the effectiveness of different rules for left-handed individuals and the practical applications of the right hand rule, but these assumptions remain unresolved.

Among its many other uses, it looks like you can use the right hand rule for screwing in a light bulb or screwing on the cap to a jug of milk!

Who said learning physics was of no practical use?

Also useful in bed - especially if you have company :D
 
So those of us who are left handed go unloved?

No way, we have it even better. I'm left handed, so if I'm taking an EM exam, I can do the right hand rule and write with my left hand at the same time! I never have to put down my pencil :cool:

Due to coriolis effects, the left-hand screw rule works better in the southern hemisphere ;)
In the northern hemisphere, lefties are advised to adopt Flemings rule instead ... the thumb still gives thrust of motion but they gain in the extent of the field and current.

Not anymore. These days they have adapters for that. A little exotic maybe, but these new neuroprosthetics are quite something to wield.

:)
 
Well it has to do with the cross product right? And the unit vectors. So that extends to all manners of torque applications.
