The plexiglas housing is filled with a special, highly viscous liquid and iron filings. After the magnet has been inserted into the central hole, the iron filings, which had previously been distributed randomly in the liquid, align themselves according to the direction of the field. An enclosed air bubble ensures that a good shake of the device causes the iron shavings to be evenly distributed.\u003cbr\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003cbr\u003e\nDiameter of the hole: approx. 21 mm\u003cbr\u003e\nDimensions: approx. 120x110x110 mm³\u003cbr\u003e\nWeight: approx. 1.48 kg\u003cbr\u003e   \u003cli\u003e\n\t\tSecure online payment with SSL\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tExpert advice\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tFinancing available\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tEasy returns \u0026amp; exchanges\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tInternational shipping available\u003c\/li\u003e\u003ch5\u003e\u003cspan\u003eSpecifications\u003c\/span\u003e\u003c\/h5\u003e\u003cul\u003e\n\u003cli\u003eUPC: Not Specified\u003c\/li\u003e\n\u003cli\u003eGTIN\/ITF Barcode: Not Specified\u003c\/li\u003e\n\u003cli\u003eUnits of Measure: Not Specified\u003c\/li\u003e\n\u003cli\u003eOverall Product Length: Not Specified in\u003c\/li\u003e\n\u003cli\u003eOverall Product Width: Not Specified in\u003c\/li\u003e\n\u003cli\u003eOverall Product Height: Not Specified in\u003c\/li\u003e\n\u003cli\u003eWeight Capacity: Not Specified lbs\u003c\/li\u003e\n\u003cli\u003eActual Product Weight: 2.09\u003c\/li\u003e\n\u003cli\u003eProduct Assembly: Not Specified\u003c\/li\u003e\n\u003cli\u003eProduct Installation: Not Specified\u003c\/li\u003e\n\u003cli\u003eCountry of Origin: Not Specified\u003c\/li\u003e\n\u003cli\u003eCase QTY: Not Specified\/case\u003c\/li\u003e\n\u003cli\u003eCase Weight: Not Specified\u003c\/li\u003e\n\u003cli\u003eShips Via Freight: Not Specified\u003c\/li\u003e\n\u003cli\u003eProposition 65 Warning: Not Specified\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3B Scientific","offers":[{"title":"Default Title","offer_id":48198980665536,"sku":"1009765","price":199.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1403\/8729\/files\/1776970919137.jpg?v=1776970922","url":"https:\/\/tensnet.com\/products\/magnetic-field-lines-device-three-dimensional","provider":"TENSnet","version":"1.0","type":"link"}
