This transparent current magnetic field demonstrator shows how direct current produces a magnetic field and how its direction relates to the current; it includes linear, circular, and solenoid modules with multi-turn coils for stronger magnetic effects, and should be handled gently, powered off after use, and cleaned with a brush.SPECIFICATION:Product Name: Current Magnetic Field DemonstratorProduct weight: 250gProduct size: 250×182×78 mm/9.84×7.16×3.07 inPurpose: Demonstrate the phenomenon of direct current passing through a wire to generate a magnetic field around it, and the relationship between the direction of the magnetic field and the direction of the current.PACKAGE:1×Current Magnetic Field Demonstrator 4×small magnetic needles2×wires1×iron powder

• 【PURPOSE】To demonstrate how direct current flowing through a conductor generates a magnetic field, and to illustrate the relationship between the direction of the magnetic field and the direction of the current.
• 【STRUCTURE】The demonstrator consists of three components—linear current magnetic field, circular current magnetic field, and solenoid magnetic field modules. Each uses multi-turn coils instead of single wires to enhance magnetic induction and improve demonstration clarity.
• 【MATERIAL】Constructed from transparent materials for clear visibility of the magnetic field distribution. Handle with care to prevent surface scratches and maintain transparency.
• 【OPERATION PRECAUTIONS】After the magnetic field lines are formed during the experiment, disconnect the power supply promptly to prevent overheating and potential damage to the device.
• 【MAINTENANCE】After each demonstration, use a soft brush to remove iron powder and keep the instrument clean for long-term use.
