Product Description

By: The Flinn Staff

Add depth to your students’ understanding of magnetism—show it in 3-D! Beautiful demonstration clearly reveals the shape and strength of the magnetic field. Simply fill the special jar-and-tube assembly with oil, add iron filings, shake, and insert a magnet. The filings line up along the magnetic field, concentrating especially at the poles where the field strength is greater. Seeing is believing, and this large-scale magnetic field is very visible—and persuasive!

Concepts: Ferromagnetic materials, magnetic field, magnetic domains, magnetic poles.
Time Required: 15 minutes
Materials Provided: Iron filings, mineral oil, powerful cow magnet, jar with drilled lid and tube.
Note: Neodymium magnets (available separately) may be used to demonstrate other magnetic field variations. Materials may be reused for many years!


Neodymium Magnet
Unbelievably strong magnet! Watch your fingers if you bring two of them together! These ceramic magnets are a perfect example of how technology is producing new materials with space-age properties. These crystalline, ceramic cobalt-neodymium magnets...
