Question

Question 1
The table below shows the farthest distance that magnets M, N, O, P can reach to pull a paper clip toward them.



Which magnet has the greatest magnetic force?

a
M
b
N
c
O
d
P
Question 2
A student is investigating magnetic fields. The picture shows what happens when the student drops iron filings on a bar magnet.



The student claims that the magnetic fields are not the same across the magnet. Using the picture, what evidence best supports the claim?

a
The magnetic fields of the magnet are strongest at the north pole.
b
The magnetic fields of the magnet are strongest at the south pole.
c
The magnetic fields of the magnet are strongest at the middle.
d
The magnetic fields of the magnet are strongest at both poles.

Answer 1

I don’t have the table/image for Question 1, so I can’t pick the specific magnet letter. General rule: the magnet that can pull the paper clip from the farthest distance has the greatest magnetic force — choose the magnet with the largest distance in the table.

Question 2 answer: d. The iron filings concentrate most strongly at both ends (poles), showing the field is strongest at both poles.
