Nakamura Magnetic Field 3D Observation Box with Alnico Magnet

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.
