Avoid friction to maintain permanent transparency; cut off power in time after induction lines take shape to prevent high temperature damage.\u003c\/li\u003e\n\u003cli\u003eAfter power connection, the magnetic powder around the solenoid will automatically arrange along magnetic induction lines. Small magnetic needles can be placed at multiple positions to accurately detect and verify the actual magnetic field direction.\u003c\/li\u003e\n\u003cli\u003eChanging the input current direction will synchronously reverse the layout of magnetic induction lines, fully complying with the right-hand screw rule. It is an essential auxiliary device for electromagnetism teaching, laboratory research and principle popularization.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"BrightMinds","offers":[{"title":"Default Title","offer_id":47690119741524,"sku":"SPH-B0H1H6JK2L","price":69.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/3590\/1780\/files\/41v3QIIlf2L._AC_SL1500_7c9bf9eb-6213-4dbe-abfe-6ddedcc65135.jpg?v=1789644941","url":"https:\/\/learnbrightminds.com\/products\/b0h1h6jk2l","provider":"BrightMinds","version":"1.0","type":"link"}
