Thimble structure enables low‑resistance rotation of the aluminum frame.\u003c\/li\u003e\n\u003cli\u003eShows key electromagnetic phenomena: relative movement between magnetic field and conductor creates induced current inside the conductor. The induced current generates Ampere force to produce mechanical motion output.\u003c\/li\u003e\n\u003cli\u003eOperate the rocker to adjust magnet rotation speed and spin direction. The aluminum frame rotates synchronously with the magnet and reverses rotation accordingly, delivering clear visible experimental feedback.\u003c\/li\u003e\n\u003cli\u003eBuilt with metal components paired with strong permanent magnet. Overall dimension: base 300×200 mm with total height 230 mm. Stable mechanical construction supports repeated lab‑based experimental operations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"BrightMinds","offers":[{"title":"Default Title","offer_id":47666914164820,"sku":"SPH-B0HHMQ8H4S","price":306.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/3590\/1780\/files\/31Kk9lW9frL._AC_SL1500_d3276ee7-35b7-4ad5-9e25-dc987b887c22.jpg?v=1789309946","url":"https:\/\/learnbrightminds.com\/products\/b0hhmq8h4s","provider":"BrightMinds","version":"1.0","type":"link"}
