Question 2
FThe Figure shows the magnetic field lines between two pairs of bar magnets, in arrangement 1 and arrangement 2.
Figure
a.[2]
Which arrangement shows two like poles facing each other?
Give a reason from the Figure for your answer.
b.[1]
State the type of force between the two magnets in arrangement 1.
c.[2]
In arrangement 2, a plotting compass is placed at point Z. The compass needle does not point in any particular direction.
Suggest why.
d.[2]
Another student uses iron filings instead of a plotting compass to show the field pattern.
Give one advantage and one disadvantage of using iron filings.
