Rectangular plastic cased iron filings to show the effect of magnetic force when in the proximity of a magnet.
Place a magnet (not supplied) on the pad and the iron filings orientate themselves to show the direction of magnetic force.
Size: 3 3/4'' x 2 3/4'' x 2/5'' (97x70x10mm).
The hard plastic case scuffs easily, hence the fantastic price we have managed to get these for.
Pack of 4 = Excellent Value!
