Scroll all the way to the bottom in the link I'll provide below and there will be diagrams for which my questions/answers are based on.
I'm having trouble applying the "right hand rule" to 1. c)
Also, for 1.a) I think the magnetic field lines should go around the conductor (i.e. curve around it, like on a target) but if you do the right hand rule thing, wouldn't your fingers be straight?
So does the field not curve around the conductor? Or can I assume that it does, and just ignore the straightness of my fingers and just use my fingers as the _direction_ of the magnetic field?
2. increase the magnitude of the external field and the current and the angle between the conductor and the magnetic field it cuts across (? - this confuses me again as it goes back to my question above as to the magnetic field lines being straight or curved...)
3. The electromagnetic field would increase, thus....?
4. a) ???
b) Yes, because electrons always move in the same direction (negative to positive) (?)
I only have to do up to #4.
