TITLE: 3-D MAGNETIC FIELD
AUTHOR: JIM L. TORGERSON, NORTH SEVIER MIDDLE
SCHOOL,;SALINA, UTAH
GRADE LEVEL: Appropriate for grades 6-8.
OVERVIEW: The students will be able to make and/or see
a magnetic field.
PURPOSE: Help students gain an understanding of
magnetic fields to prepare for understanding of magnets
and electricity.
OBJECTIVES: Students will be able to understand what a
magnetic field looks like.
BACKGROUND INFORMATION:
You will need to cover the basic concepts of magnetism
before doing this project or use this project to help
students understand magnetism. You will need the
following materials:
RESOURCES/MATERIALS:
RESOURCES:
PHYSICAL SCIENCE TEXT BOOKS; ENCYCLOPEDIA, ANY OTHER
RESOURCES THAT RELATE TO MAGNETISM AND ELECTRICITY THAT
ARE AVAILABLE.
MATERIALS:
1. Small juice drink bottle.
2. 15mm by 120 mm test tube.
3. Glue that will hold glass to metal.
4. Iron filings.
5. 12mm by 75 mm cow magnet
6. cotton balls
ACTIVITIES AND PROCEDURES:
Take the small juice drink bottle, drill or poke a hole
15 mm in diameter in the lid. Push the 15mm by 120 mm
test tube through the hole you have made. Glue in
place. Remove the contents of bottle first, hopefully
by drinking it. Wash the bottle out and dry it. Put
your iron filings in the clean bottle. Replace the lid
with the test tube glued in. Tighten up well. Put a
cotton ball in the bottom of the test tube. This will
protect the test tube from the magnet then drop in the
magnet. Put your thumb over the top of the test tube
and move the bottle around so the iron filings are
attracted to the magnet. You now have a 3-D magnetic
field.
CROSS-CURRICULUM IDEAS:
English: Write a descriptive story of what you see.
Art: Draw and color a magnetic field, make a two
dimensional magnetic field.
