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

  1. Nov 29, 2012 #1
    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?

    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.
