General Physics Science Fair Project

Temperature and Magnets

Medium
Temperature and Magnets | Science Fair Projects | STEM Projects
We'll investigate how magnets react to different temperatures. We'll measure the number of steel washers that stick to the magnet at different temperatures.

Hypothesis

The hypothesis is that increasing the temperature of a magnet reduces its strength.

Method & Materials

You will measure the temperature of the magnets, spread steel washers on a tray, and count the number of washers that stick to the magnet at different temperatures.
You will need 5 magnets, 200 steel washers, a flat tray, a hot plate, an infrared thermometer, a refrigerator, and a pair of gloves.

Results

The results showed that as the magnet's temperature increased, the number of washers picked up by the magnets decreased. This proves that increasing the temperature of a magnet reduces its strength.

Why do this project?

This science project is interesting because it explores the relationship between temperature and magnetism, which is a phenomenon that is used in many everyday items.

Also Consider

Consider repeating the experiment using an electromagnet, or using magnets made from different materials.
