Right hand rules

  1. Dec 9, 2005 #1
    We recently started learning about magnetic fields and forces in physics and we took these weird right hand rules...
    After much attempt I cannot, for the life of me, figure them out.
    Is there any way I can find the direction of the field or a force without using my right hand? Like on paper or mathematically or something? (Choosing "approximate directions" ofcourse)
    Thanks for any responses.

    The right-hand rule is a mnemonic for the cross product. The algebra of the cross product is already oriented.
    However, for quick reference, you should just use your right hand.
