Question

Julie’s town uses single-stream recycling, so Julie puts all of her household recyclables in a single container to be picked up. The recycling plant must sort out the different materials, including paper, cardboard, different types of plastic, glass bottles and jars, aluminum drink cans, and steel food cans.
How would an electromagnet be used in this type of recycling plant?

A) to remove plastic bottles from glass bottles
B) to divide food cans from soft-drink cans
C) to separate paper from cardboard
D) to gather colored
glass from colorless glass

Answer 1

Answer: Option (B) is the correct answer.

Explanation:

Steel is an alloy that is made up of different metals out of which one is iron. As it is known that iron is easily attracted towards an electromagnet.

So, an electromagnet can be used to divide food cans from soft-drink cans.

On the other hand, an electromagnet is not able to attract any plastic material, glass bottles, aluminium drink cans, paper cardboard etc. Therefore, an electromagnet will not help us to separate out any of these materials.

Hence, we can conclude that an electromagnet can be used in this type of recycling plant to divide food cans from soft-drink cans.

Answer 2

Steel is magnetic, aluminium is not. So the electro magnet would pull only the stell food cans, separating them.

Answer:

$\boxed{\bf~The~answer~is~B.}$

Hope it helped,

Happy homework/ study/ exam!
