One slug is plain steel and falls through the copper tube quickly. The other slug is a strong neodymium magnet that falls very slowly through the tube due to the braking effect of eddy currents.\u003c\/li\u003e\n\u003cli\u003eIncludes detailed activity guide with teacher activities\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"United Scientific","offers":[{"title":"Default Title","offer_id":48200054669463,"sku":"B0DX84HDT8","price":52.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/1032\/2327\/files\/21Hxz8Kx-5L.jpg?v=1788421720","url":"https:\/\/tinkervanta.com\/products\/united-scientific%e2%84%a2-eddy-current-demonstrator-12-long-1-each","provider":"TinkerVanta","version":"1.0","type":"link"}
