Track and diagram magnetic fields using a tiny compass. Fun to see how different magnets can have similar fields and how the fields of two magnets interact. Not all forces are visible. Magnetic fields are an example of an invisible force and experiments like this help students better visualize them. 

 

Use this to learn and reinforce answers to questions such as:

❑ How can we show invisible magnetic fields?

❑ What is the shape of the magnetic fields around different magnets?

❑ How does the shape of a magnetic field change when a second magnet is brought nearby?

 

Once students work through the activity, they can capture their observations using the included Lab Notes or probing questions included in the instructions. 

 

Concepts Addressed

♦  Magnetic lines of flux don't cross

♦  Magnetic lines of flux can be shown using iron filings

♦  Iron filings act like small magnets and will align themselves with magnetic field lines
