J5-06. Bar Magnet, Klinger Magnet Model, And Overhead Projector
Purpose
Demonstrate that magnet poles come in pairs.
Equipment
Broken magnet with iron filings and plastic overhead projector viewer, on overhead projector.
Suggestions
Please ask for the broken magnet; it is not necessary to break another one.

Description
The magnetic field of a bar magnet is demonstrated using iron filings on an overhead projector. The magnet is then broken and the demonstration is repeated. Each half of the original magnet has both poles, as can be easily seen.
