This may seem extremely obvious, but I'm really starting to get confused by when to use which one. My understanding is that you use the right hand rule when the force is being applied to the wire/coil (by hand for example), and you use the left hand rule when the force is a result of the field/s. But after thinking about it some more, I'm not sure how correct that is.
Could someone please tell me the difference between the two first of all, and when to use which one?
Thanks in advance!
