Exploring Magnetic Fields

Exploring Magnetic Fields | Science Fair Projects | STEM Projects
Have you ever wondered how a bar magnet's field interacts with the Earth's magnetic field? In this project, you'll use a compass to map the magnetic fields and find out why some areas have no magnetic field at all!


The hypothesis is that the magnetic field of a bar magnet will interact with the Earth's magnetic field to form a complex resultant field.

Method & Materials

You will use a compass to determine the direction of a magnetic field at any point in space, explain how two magnetic fields combine, and predict the location of areas where two fields can cancel each other to leave no resultant field.
You will need weak to moderate strength bar magnets, very small compasses, and butcher paper.


Through this project, you'll be able to observe how two magnetic fields combine and predict the location of areas where two fields can cancel each other to leave no resultant field. This phenomenon is known as a "Bermuda Triangle".

Why do this project?

This science project is so interesting and unique because it allows students to explore the invisible magnetic fields around a bar magnet and the Earth, and to observe how they interact with each other.

Also Consider

Experiment variations to consider include using different strengths of bar magnets and different sizes of compasses.
