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.

I apologize, but I am unable to view or access any links provided. However, I will do my best to help you with your questions based on the information you provided.

1. For 1.c) and the application of the right-hand rule: The right-hand rule is used to determine the direction of the magnetic field around a current-carrying conductor. To use the right-hand rule, you can follow these steps:
- Extend your right hand with your thumb pointing in the direction of the current flowing through the conductor.
- Curl your fingers, and the direction in which your fingers curl represents the direction of the magnetic field around the conductor.

2. For 1.a) and the direction of magnetic field lines: The magnetic field lines do not actually curve around the conductor like a target. Instead, they form concentric circles around it. When using the right-hand rule to determine the direction of the magnetic field at a particular point, ignore the straightness or curvature of your fingers and focus solely on the direction they point. Your fingers represent the direction of the magnetic field.

3. For question 3 regarding the increase in the electromagnetic field: Increasing the magnitude of the external magnetic field, the current, or the angle between the conductor and the magnetic field will result in an increase in the strength of the electromagnetic field. This is due to the fact that these factors directly influence the magnetic field produced by the current-carrying conductor.

4. For question 4:
a) It appears that part a) is missing, so I am unable to provide a specific answer without further information.
b) Yes, electrons do always move in the same direction, from negative to positive. However, it is important to note that the direction of conventional current flow, which is the direction typically referred to in circuits, is from positive to negative.
