Observing Magnetic Fields in Two and Three Dimensions Video Clips. Duration : 1.87 Mins.

Your days of cleaning up iron filing messes are over! The Magnetic Field Observation Window Kit and Magnetic Field Observation Box provide clean & quick ways to visualize magnetic fields. A must have for any magnetism lesson. Magnetic Field Observation Window Kit www.arborsci.com Simply place a magnet on top of the clear frame containing the magnetic particles and watch as they provide the same patterns as iron filings with none of the headaches of set up and clean up. This kit, which includes 2 plastic cased magnets, 2 ferrite magnets, and a guide full of demo ideas, is a must for any magnetism lesson and works great in combination with an overhead projector. The entire frame is 9 inch (225mm) X 5 inch (126mm) X ½ inch (13mm), perfect for placement on an overhead projector! Magnetic Field Observation Box www.arborsci.com This self-contained device reveals the proper, three-dimensional nature of magnetic lines of force. The sealed acrylic box contains iron filings suspended in a silicone oil solution. A cylindrical magnet (included) is dropped into a central chamber to create the three-dimensional field. Other magnets can be applied to the sides or ends of the box to demonstrate interesting interactions between fields. Although primarily designed for individual study, the observation box can also be placed on an overhead projector for a two-dimensional demonstration of the field (4" x 2" x 2").
