Chapter Name: Playing With Magnets
Activity Name: Finding materials attracted by magnets in Playing With Magnets
In this experiment, we will test various objects to determine if they are attracted to a magnet or not.
- Bar magnet
- Plastic scale
- Piece of glass
- Iron bolt
- Stainless steel spoon
- Piece of chalk
Step by Step Procedure:
- Take the bar magnet and gather all the objects listed.
- Touch the magnet to each object one by one.
- Observe and record your observations in a table, noting the name of the object, the materials it is made of (Iron/Plastic/Aluminium/Wood/Glass/Others), and whether it is attracted to the magnet (Yes/No).
- Repeat this process for all the objects.
|Name of the object||Materials of which the object is made||Attracted by Magnet (Yes/No)|
|Piece of glass||Glass||No|
|Stainless steel spoon||Metal||Yes|
|Piece of chalk||Calcium carbonate||No|
- Handle the magnet with care as it can be strong and may attract nearby metal objects.
- Ensure that the objects being tested are clean and free from any magnetic substances or debris.
Lesson Learnt from Experiment:
- Materials that are attracted to the magnet (such as iron, metal, and stainless steel) are called magnetic materials.
- Materials that are not attracted to the magnet (such as plastic, wood, glass, and paper) are called non-magnetic materials.
- Some examples of magnetic materials include iron nails, jump-clips, keys, iron bolts, blades, knives, and stainless steel spoons.
- Some examples of non-magnetic materials include plastic scales, glass, paper, pens, pencils, wooden objects, and pieces of chalk.
- The property of magnets attracting certain materials can be utilized for separating mixtures based on magnetic properties.
