Question 2

Answer to Question 1

The nonmagnetized iron bar will neither attract nor repel the center section of the
magnetized bar, but the magnetized iron bar will attract the center section of the
nonmagnetized bar.

Answer to Question 2

If lines of magnetic force crossed one another, the point of intersection would show
two different directions of the magnetic field at the intersecting point. This is
impossible.
