About This

• Core Electromagnetic Experiment Verification: This demonstrator is professionally used to prove the existence of a magnetic field around a current-carrying conductor, and can complete the verification of linear current magnetic field and Oersted experiment effectively.
• Standardized Experimental Placement: Place the device on a flat table, mount the large magnetic needle on the tip, and adjust the base to keep the wire parallel to the stationary magnetic needle for accurate experimental observation.
• Intuitive Magnetic Field Phenomenon Display: After connecting 6V DC power supply, the magnetic needle deflects obviously, directly proving the current-generated magnetic field, and the right-hand rule can be used to judge the magnetic field direction.
• Current Direction Contrast Test: By reversing the current direction, the synchronous change of the magnetic needle's deflection direction can be observed, clearly showing the correlation between current and magnetic field direction.
• Practical Physics Research Tool: The experimental operation is interactive and intuitive, which helps to improve practical operation and observation ability, and connects electromagnetic theory with real experimental phenomena closely.
