Introduction
In this experiment, we will be determining the relation between magnetic strength and temperature to see whether a magnetic force gets affected by varying temperatures.
Aim
To check the dependence of magnetic strength on changing temperature.
Theory
We hypothesized that the high temperature decreases the magnetic strength for performing this experiment.
Requirements
1. Paperclips
2. Two bowls filled with water
3. Dry ice
4. Ice
5. Containers
6. Small Pot
7. Four magnets
8. Notebook
9. Thermometer
Procedure
Step 1: Take a pot and put some water into it.
Step 2: Take two plastic containers and add dry ice and ice into them.
Step 3: Put the pot water to boil.
Step 4: Add a magnet to the pot and each of the containers.
Step 5: Leave one magnet at room temperature. It will act as the controller.
Step 6: Take a plastic bowl.
Step 7: Put at least 200 paper clips in this bowl.
Step 8: After 10 minutes, remove the magnets from the container bowls at room temperature.
Step 9: Place each of the magnets in the bowl.
Step 10: Take out the magnets from the bowl and count the number of paper clips each magnet has attracted.
Step 11: Record your observations in a notebook.
Observation
1. In our observation, we saw that there is a relation between magnetic strength and temperature and that magnetic force does get affected by varying temperatures.
2. The magnet we placed in hot water attracted fewer magnets compared to those placed in different places.
3. This means that on increasing temperature, magnetic strength decreases.
Result
1. Our hypothesis, in which we assumed that temperature affects magnetic strength, was right.
2. The magnet which was placed in hot water got affected more than all.
3. The magnet which was placed in ice attracted the most paperclips and got affected the least.
4. It means that magnetic strength is inversely proportional to temperature. This means that on increasing temperature, magnetic strength decreases. And on decreasing temperature, magnetic strength increases.
Precaution
1. Wear gloves while touching hot magnets.
2. Count the number of paper clips carefully.
Conclusion
In this experiment, what is the relation between magnetic strength and temperature. We determined whether or not magnetic strength gets affected by changing temperature by counting the number of paper clips.
