3D Magnetic Field Observation Box

This sealed acrylic observation box reveals magnetic fields the way only 3D presentations can! With iron filings suspended in a solution, students create three dimensional lines of force simply by dropping a cylindrical magnet (included) into the central chamber. They can produce amazing interactions between the fields by applying other magnets to the sides or ends of the box. Though designed for individual study, the box can be placed on an overhead projector for a two dimensional demonstration with no filings to clean up: 3" x 3" x 3" cube. Activities and usesUse the 3D Magnetic Field Observation Box to study magnetic fields in three dimensions. Look at the field from a single provided magnet or bring iron or another magnet near and see the results. A sample activity from the instructional guide is given below. Bring another magnet close to the box and insert the bar magnet in the hole. The iron powder is magnetized in two areas showing attraction and repulsion of magnetic forces.
