Broad Question
Does the temperature affect the strength of magnets?

Specific Question
Is magnet strength affected by temperature?

Hypothesis
I believe that the higher the temperature is around a magnet, the lower the magnets strength will be.

General Plan
My General Plan is to find out if heat affects magnet strength. I will test this by putting magnets in a hot area, room temperature, and in a cold area. After the magnets are the right temperature I will hold the magnets over a certain amount of paperclips. I will test how strong the magnets are by recording the amount of paperclips attracted.

Experimental Design
I am conducting an experiment to see how varied temperature effects magnet strength. I will be conducting my experiment at my own house. There will be only one person involved in the experiment. I am the only person involved in the experiment. I will be conducting only one trial. I believe one trial is enough to gather the right amount of information. I will be recording my data on a spreadsheet on the computer. This way I can record it all then print it. I will be documenting the process of my experiment. I plan to document my experiment with photos and written information. I will take the photos then upload them at school and save them to my x-drive. Once the photos are saved into my x-drive I will be able to upload them to my Wiki page. I will also print out some of the photos to display on my poster.

Materials list

 * Magnets
 * Thermometer
 * Heat source
 * Camera
 * Spreadsheet
 * Pencil
 * Metal Surface

Detailed Procedure

 * 1) Gather Materials.
 * 2) Attach magnet to metal surface.
 * 3) Place thermometer near magnet.
 * 4) Have heat source heat up magnet and surface.
 * 5) Take photo of setup.
 * 6) Record data.
 * 7) Repeat steps two more times.

Background Research
When a magnet is heated to a certain point, known as the Curie point, it loses all of its magnetism. The magnet also doesn’t work when it is cooled, but it can often be re-magnetized. Some magnets break at high temperatures though. Magnets can only be magnetized at up to 1,000 °F.
