THREE DIMENSIONAL DEMONSTRATION OF THE MAGNETIC FIELD
The Magnetic Field Observation Box is the perfect way for students to observe magnetic force fields. Watch the creation of a magnetic field in 3 dimensions in your hand or via on overhead transparency. The sealed acrylic box contains iron filings suspended in a silicon oil solution. When the cylindrical magnet (included) is inserted into the central chamber, the filings immediately align to create a 3-dimensional field. U-shaped magnets and electromagnets can be used on the outside of the box to demonstrate this magnetic principle.
