Magnetic Field Pattern Window
Product Information
A white frame with transparent window containing magnetic powder in a water based solution for showing magnetic field patterns.
When a magnet is present the particles of iron inside become slightly magnetised, so they attract each other and cluster into the lines that show the magnetic field patterns.
Includes a pair of small ferrite block magnets and a pair of plastic-cased bar magnets and teachers leaflet.
