Demonstration apparatus for the properties of the crystal lattice of ferromagnetic materials, particularly Weiss domains, Barkhausen jumps, saturation, hysteresis and Curie temperature.
118 freely moving magnetic needles are supported in a hexagonal arrangement between two connected transparent acrylic plates. For projection on the overhead projector.
Length of magnetic needles: approx. 11 mm
Dimensions of plate: approx. 150x150 mm²
