The plate is suitable for displaying planar or spatial magnetic fields instead of iron powder. Scratch-resistant, transparent plastic plate in which metal pins are inserted at regular intervals, which arrange themselves into the typical magnetic field images when a magnet approaches. The soft iron pins used have the advantage over magnetic needles that they actually show the expansion of a magnetic field due to friction and cannot be remagnetised by a strong magnet. Suitable for overhead projection. Technical data Number of pin fields: 100 Length of the pins: 8 mm Dimensions: 177 x 177 x 8 mm
