Read the following case carefully and answer the questions that follow.
Three students observe the magnetic field around three straight current-carrying conductors from above.
Conductor \(X\): Current flows upward.
Conductor \(Y\): Current flows downward.
Conductor \(Z\): Current flows upward.
They apply the Right-Hand Thumb Rule to determine the direction of the magnetic field around each conductor.
Conductor \(X\): Current flows upward.
Conductor \(Y\): Current flows downward.
Conductor \(Z\): Current flows upward.
They apply the Right-Hand Thumb Rule to determine the direction of the magnetic field around each conductor.
1. Which conductors will have the magnetic field in the same direction?
2. What will be the direction of the magnetic field around conductor \(Y\) when viewed from above?
3. If the current in conductor \(Z\) is reversed, which conductors will now have magnetic fields in the same direction?
4. Which statement best explains the above observations?
