It is a translucent paper-like substance which makes magnetic fields visible. Most are made from a plastic film that contains a ferromagnetic slurry of fine nickel particles that align themselves along magnetic field lines. The general principle of operation is that magnetizable nickel particles are suspended in a colloidal form in a gelatinous material. This allows enough freedom for the particles to align with an externally applied magnetic field - thereby displacing the colored fluid and causing a color change at the surface of the film. Recommended for ages 8 and older.\u003c\/p\u003e","brand":"Applied Magnets","offers":[{"title":"Default Title","offer_id":45236980154483,"sku":"WBIASB00129CCGS","price":23.86,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0643\/1958\/6419\/files\/71DUpafzRpL.jpg?v=1784031060","url":"https:\/\/slickpurchase.com\/products\/super-strong-magnetic-viewing-film-multiple-sizes-for-magnet-field-detection-6x6","provider":"Slickpurchase","version":"1.0","type":"link"}
