During the demonstration, after the magnetic induction line is formed, the power should be cut off to avoid excessive temperature and damage the instrument. After the experiment, the iron powder is brushed with a brush.\u003c\/li\u003e\n\u003cli\u003eThe solenoid magnetic field uses a solenoid coil to demonstrate the external circuit. After energization, the iron powder around the solenoid is arranged in a magnetic sense line according to the direction of the magnetic field. The small magnetic needle is placed at each position to verify the direction of the magnetic field. .\u003c\/li\u003e\n\u003cli\u003eChanging the direction of the current, the direction of the magnetic induction line also changes, and the relationship of the direction is also in accordance with the right-handed screw rule.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"BrightMinds","offers":[{"title":"Default Title","offer_id":47666909872212,"sku":"SPH-B0F6SSS1PG","price":49.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/3590\/1780\/files\/31IZ3zeVPDL._AC_SL1500.jpg?v=1789309926","url":"https:\/\/learnbrightminds.com\/products\/b0f6sss1pg","provider":"BrightMinds","version":"1.0","type":"link"}
