The Strength of an Electromagnet
Science Fair Project Idea
Scientific Method
You may be familiar with permanent magnets—the kind that hang on a refrigerator. But did you know that other magnets, called electromagnets, can be turned on and off? When turned on, electromagnets act just like permanent magnets, but if you turn them off, their magnetic properties disappear. Electromagnets are an important part of many electronic devices, like motors, loudspeakers, and hard drives. You can create an electromagnet with a simple coil of wire and a battery. In this project,… Read more
Measuring Magnetic Fields
Science Fair Project Idea
Scientific Method
Have you ever noticed how magnets appear to have no effect on each other when they are far apart? Then, when you slowly move them closer together, you will start to feel a gentle pull until they suddenly snap together? How exactly does the strength of a magnet change with distance, and how would you measure it if you wanted to find out? In this project you will build a circuit that can measure the strength of a magnetic field and see how the field strength changes with distance. Read more

Making an electromagnet from a battery, nail, and wire is a classic science demonstration. But instead of just demonstrating this for your students, let them explore it themselves! In this lesson they will discover how different variables affect the strength of an electromagnet. Read more
NGSS Performance Expectations:
  • MS-PS2-3. Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.
