:confused: Ooops. My mistake on the force part (was thinking of something else), but I'm going to stick to the work thing for now (given the same scenario).
Let me take this down the road a bit. All four of the fundamental forces involve the exchange of one or more particles. Even the...
Nice job, John. And you could not be more correct: Never give up. If you have the passion and the drive nothing can stop you. Chem, he gives great advice so stick to it. I had a similar experience but pulled it out and starting this year will be teaching physics. Good luck!
Agreed to a point. But it's not a force and no work is done. Like gravity, another fundamental force, there is something lurking below the surface, the graviton. In the relationship I described the moving particles, either in the wire or out, move perpendicular to the external field...other...
Thanks to both...and kuenmao, that's as far as most people go..."that's just the way it is." I want the nitty gritty. Why? Comparing it to just a particle passing through a magnetic field we get the same result: it moves up or down, perp to the field, depending on charge. But why? Is it...
By passing a wire through a magnetic field and running a current through it I can get the wire to move perpendicular to the field. Why? Specifically, is it the reaction of the magnetic field it is passing through interacting with the magnetic field generated by the wire itself? ...The devil...
If the field and the velocity are the same the only difference is in the direction that your thumb is pointing (force). For students new to physics, is it more confusing to suggest they remember to switch the direction of the force in their minds as opposed to using their left hand? ...Fleming...
All of the books and experience I can find offer only a Right Hand Rule for magnetism (current in a wire, particles). Since this is good for only positive particles, students must remember to switch the direction of the force when using the rule. Why not just use the left hand for negative and...
