Answer;
- the direction the wire moves in
- the direction of the magnetic field
Explanation;
The direction of an electric current is also the direction in which a positive charge would move.
The direction of flow of electric current in a current carrying conductor such as a wire depends on a number of factors. These factors includes; the direction the wire moves in; that is current will flow towards the direction of a given wire or conductor.\
Secondly, the direction of magnetic field determines the direction of flow of electric current; this can be explained by the idea of induced current; the direction of induced current depends on the direction of magnetic field according the Fleming,s right hand rule.
