Milestone Formal PresentationTopicThis year, for my milestone project, Ive done an experiment on how temperature affects the magnetic field of a magnet. Magnets have always amazed me from being able to attract metals, like iron to repelling one another. In fact, I could not believe the Earth was a giant magnet when I found out. I really wanted to gain a better understanding on them, so I chose to do this project. My testable question for the experiment is How does the temperature of a magnet affect the amount of iron filings it attracts?HypothesisSo, before I constructed my hypothesis, I did some Background research. This helped me understand more about magnets. The hypothesis I made was, If I increase the temperature of a magnet, then its magnetic field will weaken because according to my research, when a magnet heats up, its electrons start moving rapidly, therefore weakening its magnetic field.Testable QuestionAs I stated before, My testable question is, How does the temperature of a magnet affect the amount of iron filings it attracts? Background ResearchFrom my background research, I have learned many facts, but these are just a few that are important. I have learned from my research that a magnet can repel other magnets as well as metals. So, magnets with opposite poles repel. Also, the shape of the magnetic field can be changed by changing the shape of the magnet. So, if I had a bar magnet, the magnetic field would be shaped differently than a magnetic field of a horse shoe magnet. Finally, I learned magnets have a magnetic field, which weakens or becomes stronger if you increase or decrease the temperature. This piece of information especially helped me support my hypothesis. Until I did background research, I had limited knowledge on magnets.MaterialsFor my experiment, I used 5 magnets, iron Filings, regular Ice, dry Ice, 5 beakers, a pot, a ruler, a thermometer, a spoon, and waterProcedureIn the procedure, first I gathered five beakers and a pot. Second, I added dry ice and a magnet to a beaker and placed it in the freezer, where I set it at -30F. Third, I poured regular ice and a magnet to another beaker and placed it in a different freezer. Fourth, I added a magnet to the third beaker and placed the beaker in the fridge at 37 degrees Fahrenheit. In the fourth beaker, I placed the magnet and put the beaker on the counter for room temperature. Sixth, Iused a thermometer to measure temperature.Procedure, ContinuedSeventh, I placed all the iron filings in the fifth beaker. After 2 days, I boiled a pot of water and placed one magnet in it. I used a ruler to measure 3 inches away from the magnet. Next, I took out all the magnets from their spots one at a time and placed them 3 inches above the iron filings. Eleventh, I returned all magnets back to their original place. Finally, I repeated steps 7 to 11 three times at least.Data TableIn the table, as you can see, the magnets at a higher temperature attracted the least amount of iron filings. The average of the magnet at 110F is 1 gram whereas the average of the magnet at -30F is 10.3 grams.GraphIn the graph, it is clear that the dry ice magnet attract ted more iron filings than the boiling water magnet.Results
