Question
Some rocks contain small amounts of iron. These rocks have magnetic properties. The iron particles act like tiny magnets that are attracted by the two oppositely charged magnetic poles of Earth.
A student uses a toy that has a wand with a magnet on the tip and iron filings to add “hair” to a face. As the student moves the wand across the plastic cover, the iron filings sprinkled on the face below follow the movement.
Which change in the design of the toy would allow the student to move more iron filings with the wand at one time?
Responses
A Use a wand with a more powerful magnet.Use a wand with a more powerful magnet.
B Make the iron filings a different color.Make the iron filings a different color.
C Make the sheet of plastic thicker.Make the sheet of plastic thicker.
D Use more iron filings in between the cardboard and plastic.Use more iron filings in between the cardboard and plastic.

The best change in the design of the toy that would allow the student to move more iron filings with the wand at one time is:
**A** Use a wand with a more powerful magnet.
A more powerful magnet would have a stronger magnetic field, which would be able to attract and move a greater number of iron filings at once. The other options do not directly improve the ability of the wand to move the filings effectively.
