Instructional Ideas
  • Do the activity on a transparency so you can project it
  • Use iron filings on one of the recording sheets with the magnet underneath it to show another way to visualize the magnetic field
Classroom Considerations
  • The class should understand what kinds of materials magnetic fields affect
  • Fourth of an eight-part series
  • The worksheet helps guide pupils as they draw the magnetic fields
  • The materials list includes information on where to get the materials if you do not already have them
  • None
