This micro-encapsulated film enables students to view a static magnetic field, such as found around permanent magnets or DC electromagnets. Simply place the film directly on the surface of the magnetic material in question and instantly reveal a magnetic field of any shape or pattern. You can easily identify the poles. The film is highly flexible and quite durable. It can be laminated. Available as 12 x 12 in., 6 x 6 in., or a 1 x 36 in. strip
perfect for use with our Eddy Current Tubes. The film is shown above with a ring of our small Neodymium Spheres (not included).
