About This

• 1. This professional Oersted experiment apparatus verifies the classic electromagnetic core principle, effectively proving magnetic field existence around current-carrying conductors and demonstrating magnetic field distribution features of linear current.
• 2. Adopts precise structural design with adjustable base and sensitive magnetic needle. Align the conducting wire parallel to the static magnetic needle to ensure accurate experimental setup and reliable test data.
• 3. Compatible with standard 6V DC power supply. Obvious magnetic needle deflection occurs after power connection, intuitively presenting current-induced magnetic field effect and supporting right-hand rule verification for magnetic field direction judgment.
• 4. Supports contrast experimental tests by switching current directions. The reversed deflection of the magnetic needle clearly reflects the correlation between current direction and magnetic field orientation.
• 5. Features stable performance and prominent experimental phenomena. Compact integrated structure ensures convenient operation, ideal for exploring basic electromagnetic induction laws and current magnetic field mechanics.
