- 3-Dimensional Magnetic Field Demonstrator.
- The classic demonstration of magnetic lines of force uses iron
filings spread on a piece of paper with a magnet underneath. That method
allows the observer to see some lines of force - but primarily in only 2
dimensions. However, lines of magnetic force emanate in all three
physical dimensions. This 3-D Magnetic Filed Demonstrator uses iron
filings in a clear acrylic case to show the full magnetic field of the
included test magnet. Simply shake the demonstrator up and down and the
iron filings will form around the magnet in stunning detail.
Additionally, the case hinges opens to reveal the cylinder magnet inside
the unit. Opening the case also allows the viewer to simultaneously see
the lines of force in 3-D and a 2-D cross section. The magnet can also
be removed and used independently of the demonstrator. The filings are
completely sealed in the case at all times, whether closed or open, and
the filings never need to be replaced. The 3-Dimensional Magnetic Field
Demonstrator is a fantastic learning tool.
- Dimensions: 5 x 5 x 5 inches (Closed)
