Avoid friction and maintain its transparency.\u003c\/li\u003e\n\u003cli\u003eDuring the demonstration, after the magnetic induction line is formed, the power supply should be cut off to avoid excessive temperature and damage to the instrument.\u003c\/li\u003e\n\u003cli\u003eAfter the experiment, the iron powder should be cleaned with a brush.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"BrightMinds","offers":[{"title":"Default Title","offer_id":47666924093524,"sku":"SPH-B0DFWHC57K","price":82.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/3590\/1780\/files\/410RH01R3DL._AC_SL1500_75ae6f41-2c3c-41fb-a73d-db9760b611fa.jpg?v=1789309991","url":"https:\/\/learnbrightminds.com\/products\/b0dfwhc57k","provider":"BrightMinds","version":"1.0","type":"link"}
