Question

When an electric current is flowing through a wire, the force deflecting the charged particles is greatest when the wire is _________ to the magnetic field.
Responses
A parallelparallel
B diagonaldiagonal
C perpendicularperpendicular
D at a 30° angle

Answer 1

The force deflecting the charged particles in a wire carrying an electric current is greatest when the wire is **C perpendicular** to the magnetic field. This is described by the right-hand rule and the formula for the magnetic force on a current-carrying wire, which states that the force is maximized when the angle between the wire and the magnetic field is 90 degrees (perpendicular).
