question 3 (1 point)
when you click the change direction button, you change the direction of the current. what happens to the motion of the armature?

Explanation:

The armature's motion in a motor (e.g., DC motor) depends on the interaction between magnetic fields and current - carrying conductors (Fleming's Left - Hand Rule: \( \vec{F}=I\vec{l}\times\vec{B} \), where \( F \) is force, \( I \) is current, \( l \) is length of conductor, \( B \) is magnetic field). When the direction of the current is reversed, the direction of the force on the armature conductors (which drives the armature's motion) also reverses. So the direction of the armature's rotation (motion) reverses.

Answer:

The direction of the armature's motion (rotation) reverses.
