How Temperature Affects the Strength of Magnets Reuben, Neil, Shaun, Herng Yi Reuben, Neil, Shaun, Herng Yi

To find out the effects of temperature on magnets, We conducted an experiment. Here is our procedure. 1. Mark the place on the table where the paper clip is. 2. Put the magnet some distance away from the paper clip, with 1 pole facing. 3.Slowly move the magnet nearer to the paper clip, with constantly 1 pole facing it. Stop when the magnet attracts the paper clip. Measure the distance between the marking in step 1 and the magnet and record it down.

4. Repeat steps 2—3 two more times. 5. Fill the beaker with 200ml of water. Place the magnet & thermometer in the water. 6. Put the beaker in the cooler box and fill it with ice. Cool the beaker for 1 minute. Stop the cooling. Record the temperature. 7. Repeat steps 2—4 quickly. 8. Repeat steps 5—7 but use 2 minutes, 4 minutes then 6 minutes for each repetition for step Repeat steps 5—8, but heat the water with the hotplate instead.

Our Findings The strength of the magnet is weakened as heat is added or taken away. This is because of the structure of the magnet. Each atom of a magnetic metal has a North Pole and a South Pole. At first, the poles are all pointing in different directions, so there is no overall magnetism. When it is magnetised, the poles are aligned to face a certain direction. This causes them to pull/push together in the same direction, thus they have a net magnetism.
