the left side of the armature in an electric motor is pushed down. when the current changes direction, how is the motion of the armature affected?\no it is pulled up on the left side.\no it is pulled up on the right side.\no it is pulled toward the commutator.\no it is pushed away from the commutator.

Answer

Answer:

A. It is pulled up on the left side.

Brief Explanations:

In an electric - motor, the force on the armature is determined by the direction of the current and the magnetic field (using Fleming's left - hand rule). When the current direction changes, the direction of the force on the armature also changes. If the left - side was initially pushed down, reversing the current will cause the left - side to be pulled up.
