Magnetic Field Pattern Window - 21ENC00017

Magnetic Field Pattern Window

• 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.
