Project Info

        Project Summary:

The goal of my project is to answer the following question:  If different types of magnetic metals are heated up, will it affect their magnetism? The three metals that were tested are nickel steel and iron. My hypothesis is: If I heat up the metals iron, steel, and nickel, they will remain magnetic.

The independent variables in this project are the metals chosen, the temperature they are heated up to, and the power of the magnet used. The dependent variable is whether or not the magnet will attract to the metals and if so the degree of attraction. After experimenting I discovered that though steel and nickel had no noticeable change in magnetism after fifteen minutes of heating, iron had lost almost all it’s magnetism by then.
