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
This can be used for showing magnetic field patterns either on the bench or on a overhead projector
Alternatively, the device may be placed over a piece of white paper to provide background
It may be used to show fields in much the same way as with loose iron filings on card but with much greater convenience
Supplied with two pairs of bar magnets and an instruction/experiment booklet
Dimensions: 225 x 130 x 15mm
WARNING! Not Suitable for Children under 3 years due to small parts
This product contains magnets or magnetic components
Magnets can cause serious or fatal injury if swallowed
