\u003cstrong\u003efield lines\u003c\/strong\u003e surrounding a magnet. This is a \u003cstrong\u003ebuild-it-yourself science kit\u003c\/strong\u003e that includes a \u003cstrong\u003eclear bottle\u003c\/strong\u003e with a \u003cstrong\u003emetal screw cap\u003c\/strong\u003e, a small clear tube, a \u003cstrong\u003ebag of black magnetic particles\u003c\/strong\u003e, and \u003cstrong\u003etwo magnets\u003c\/strong\u003e. Simply fill the bottle with a clear liquid (not included), pour in the particles, and seal it tightly. Then bring the magnets close to the wall: the particles stand up in \u003cstrong\u003ebristling spikes\u003c\/strong\u003e, align, move with the magnet, and reveal the three-dimensional shape of the magnetic field. A simple \u003cstrong\u003ephysics experiment\u003c\/strong\u003e that requires no batteries or electricity and can be done with family, in class, or at a desk. Once assembled, the bottle becomes a \u003cstrong\u003escientific object\u003c\/strong\u003e that is fun to manipulate over and over again.\u003c\/p\u003e\n\n\n\u003cdiv class=\"aa-mat\"\u003e\n\n\u003ch3\u003eThe magnetic field, finally visible\u003c\/h3\u003e\n\n\u003cp\u003eEvery magnet is surrounded by an invisible \u003cstrong\u003emagnetic field\u003c\/strong\u003e that extends from one pole to the other. As early as the 18th century, physicists came up with the idea of sprinkling \u003cstrong\u003eiron filings\u003c\/strong\u003e around a magnet: each grain becomes magnetized in turn and aligns with the field, creating a series of curved lines. This is the famous \"map\" of field lines found in physics textbooks.\u003c\/p\u003e\n\n\u003cp\u003eThe POLARIS kit recreates this experiment in three dimensions. In the liquid, the \u003cstrong\u003emagnetic particles\u003c\/strong\u003e are free to move: they stack up along the field lines and form \u003cstrong\u003espikes\u003c\/strong\u003e where the field is strongest, near the magnet's poles. Move the magnet, or bring a second one close: the pattern changes instantly, showing how two fields combine.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003ch3 class=\"aa-title\"\u003eWhy you'll love it\u003c\/h3\u003e\n\n\u003cdiv class=\"aa-ben\"\u003e\n\n  \u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eYou build it yourself\u003c\/span\u003e\u003cspan class=\"ds\"\u003eFill, pour, screw: the assembly is part of the experience.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n  \u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003e3D magnetism\u003c\/span\u003e\u003cspan class=\"ds\"\u003eThe particles stand up in spikes around each magnet.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n  \u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eTwo magnets included\u003c\/span\u003e\u003cspan class=\"ds\"\u003eCompare a single pole, two opposite poles, or two identical poles.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n  \u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eNo batteries or electricity\u003c\/span\u003e\u003cspan class=\"ds\"\u003eNothing to plug in: only the magnets move the particles.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n  \u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eEducational\u003c\/span\u003e\u003cspan class=\"ds\"\u003eA concrete illustration of the field lines seen in physics class.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n  \u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eReusable\u003c\/span\u003e\u003cspan class=\"ds\"\u003eOnce the bottle is sealed, the experiment can be repeated as often as you like.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003ch3 class=\"aa-title\"\u003eThe POLARIS spirit\u003c\/h3\u003e\n\n\u003cdiv class=\"aa-des\"\u003e\n\n\u003cp class=\"t\"\u003eSeeing the invisible\u003c\/p\u003e\n\n\u003cdiv class=\"x\"\u003e\n\n\u003cp\u003eWe've known since school that magnets attract iron.
