The pupil\/student understands that the observed slower falling speed of the magnet is due to the eddy currents generated and the resulting magnetic field, which counteracts the falling movement of the magnet.","brand":"3B Scientific","offers":[{"title":"Default Title","offer_id":49419123884309,"sku":"3BS1009716","price":89.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/U30086_01_1200_1200_Lenzs-Law-Copper-Tube-to-illustrate-the-induction-of-eddy-currents.jpg?v=1761027733","url":"https:\/\/unitedsupplycorp.com\/products\/lenzs-law-copper-tube-to-illustrate-the-induction-of-eddy-currents","provider":"United Supply Corp.","version":"1.0","type":"link"}
