Magnetic field viewer paper
Click Image for Gallery
A simple yet effective demonstration of magnetic fields using an impressive new material which responds visually to any magnetic field placed nearby. The ‘paper’ consists of a thin plastic sheet which has tiny cells containing colloidal iron. When a magnet is placed close to the paper the iron in each of the cells will align, and form a pattern on the paper. Great for placing a strip around the Eddy Current/Lenz’s Law apparatus, to watch the progress of the magnet down the tube! The paper comes in pieces approx. 28 x 28 mm and can be cut using scissors if required.
