Question

What affects the direction of the current moving through a wire? Check all that apply.

the direction the wire moves in
the thickness of the wire
the direction of the magnetic field
the type of magnet
the direction of the needle on an ammeter

Answer 1

the direction the wire moves in

the direction of the magnetic field

Answer 2

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.
