MAGNETIC FIELD DEMONSTRATOR – ROUND COIL THROUGH BASE electricity Capacity (mL): 1000A round coil that provides the magnetic field pattern of 2x conductors passing through a surface with current passing up in one and down in the other. Can be used on an overhead projector. Designed to be used with mini 'plotting compasses', but fine iron filings can show the patterns if the surface is tapped to vibrate the iron particles. Genuine IEC product. Size (approx.): 140 x 96 x 83mm. Designed and made in Australia. Instruction Sheet included.
