It was observed that a pencil sharpener gets attracted by both the poles of a magnet although its body is made of plastic. Name a material that might have been used to make some part of it.
Given:
An observation is that a pencil sharpener gets attracted by both the poles of a magnet although its body is made of plastic.
To do:
To name a material that might have been used to make some part of it.
Solution:
Parts used in making a pencil sharpener:
A pencil sharpener's body is made up of plastic and its blade is made up of iron. So, two materials are used to make a pencil sharpener-
1. Plastic-
Plastic is a non-magnetic material because it is not attracted by magnets. Materials that are not attracted by a magnet are called magnetic materials.
Examples of non-magnetic materials:
Plastic, wood, glass, paper, etc.
2. Iron-
Iron is a magnetic material because it is attracted by magnets. Materials that are attracted by a magnet are called magnetic materials.
Examples of magnetic materials:
Iron, nickel, cobalt, etc.
Conclusion:
Although a pencil sharpener's body is made up of plastic, its blade is made up of iron. And we know that iron is a magnetic material that gets attracted to magnets. This is why a pencil sharpener gets attracted by both the poles of a magnet although its body is made of plastic.
