Science Fair Projects About Effects of
Weather Temperature on Electromagnets

Electromagnet Tips

When you are conducting electromagnetism science fair experiments it is important to remember that electrical current can create magnetic fields and magnetic fields can create electrical currents. This means that there may be forces in your natural environment that may interfere with your results.

PURPOSE

The purpose of this experiment was to determine the effect of different temperatures on the strength of electromagnets.

I became interested in this idea when I was wondering how a doorbell worked. Someone told me that there were little electromagnets in each doorbell. I wanted to figure out if doorbells worked better in colder temperatures or warmer temperatures

The information gained from this experiment could benefit people who have businesses containing electromagnets so they know what weather or temperature electromagnets work better in.

HYPOTHESIS

My hypothesis was the warmer the electromagnet was, the stronger it would be.

I based my hypothesis on the fact that the colder things are the less energy the molecules have and the warmer the molecules are the more energy they have.

EXPERIMENT DESIGN

The constants in this study were:
• The materials used to build the electromagnets
• Brand of the batteries
• Same volt batteries
• Age of Batteries
• Items picked up (staples)

The manipulated variable was the temperature of the electromagnet.

The responding variable was how much mass the electromagnet could pick up.

To measure the responding variable I determined the mass it could lift by counting how many large staples the electromagnet could pick up.
