Magnetic Fields
Describe the invisible area where a magnet's force acts.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 61
- Welcome to Magnet Mountain! A magnet's force reaches out into the area around it. That area is its magnetic field.
- You can't see a field, but this drawing shows its shape. The lines curve from one end, or pole, to the other. Iron filings line up the same way.
- The field is strongest near the poles, and it gets weaker farther away.
- Remember: magnets pull iron and steel, not every metal.
Georgia Standards of Excellence in Science:
- S5P3.b — Plan and carry out an investigation to observe the interaction between a magnetic field and a magnetic object. (Clarification statement: The interaction should include placing materials of various types (wood, paper, glass, metal, and rocks) and thickness between the magnet and the magnetic object.)
