This classroom demonstration device is perfect for understanding the patterns created by magnetic lines of force. The viewer is a flat and sealed clear plexi-box filled with iron filings dispersed in oil. The iron filings float in a layer of the oil and orient themselves according to the mangetic force of any magnet placed under the apparatus. The lines of force can be displayed for the whole classroom to see via use of an overhead projector. Excellent for entry-level earth science and magnetic experiments.
Features:
- Flat and selaed clear plexi-box filled with iron filings dispersed in oil
- When a magnet is placed on top or beneath the viewer, the filings orient themselves according to the lines of force
- Great for use in earth science classrooms
- Size: 8-3/4 x 4-3/4 x 7/16 inch

Customer Reviews
Fun, instructive, not messyMichael Rathbun from Texas
Having done the iron filing / paper / magnet exercise sixty years ago, I enjoy much fiddling with some of the newest magnetic items.
