To determine what the three numbered vectors represent using the right-hand rule, we need to understand the conventional representation of the right-hand rule in the context of electromagnetism.
- Electric Current (I): Usually represented by the direction of the current flow (the flow of positive charge).
- Magnetic Field (B): Represented by the direction of magnetic field lines; when fingers of the right hand curl in the direction of the current, the thumb points in the direction of the magnetic field.
- Force (F): The magnetic force on a current-carrying conductor can be determined by extending the thumb in the direction of the current (I) and the fingers in the direction of the magnetic field (B); the palm then points in the direction of the force.
Based on this understanding:
- If vector 1 represents the current,
- Vector 2 represents the magnetic field,
- Vector 3 represents the force,
Then, the correct choice would be:
B: 1) electric current; 2) magnetic field; 3) force.
