Electricity and magnetism are inseparable twins among natural forces. In 1820, Oersted's experiments revealed for the first time a truth that reaches the very core of the physical world: a flowing electric current produces a circular magnetic field around it. Its direction is determined by the right-hand rule, and its strength is directly proportional to the magnitude of the current. This discovery laid the cornerstone of electromagnetism and is the root of electric motors, generators, and all modern electrical technologies. Understanding "electricity generating magnetism" means understanding how the most fundamental driving force of our electrified civilization emerges from the invisible movement of electric charges. Our "Electricity Generating Magnetism" exhibit, on an open experimental platform 2.8 meters wide and 2 meters high, transforms this historic discovery into an exploration that everyone can replicate. You can smoothly adjust the current flowing through the central wire by rotating a knob. Immediately, you will see a noticeable deflection of the compass needle placed next to the wire—the most direct proof of the existence of a magnetic field. Reversing the current direction by flipping a switch also reverses the direction of the needle deflection, vividly verifying the correlation between the direction of the magnetic field and the direction of the current. You can also sprinkle iron filings on the glass plate covering the wires and tap it gently. The iron filings will magically arrange themselves into clear concentric ring patterns, visually "drawing" the shape and distribution of magnetic field lines. Our company firmly believes that the most profound scientific enlightenment comes from hands-on operation and firsthand observation. We excel at designing safe, intuitive, and inspiring interactive installations from classic physics experiments that have changed the world, such as "electricity generating magnetism." If your science museum, school laboratory, or public education space needs a core exhibit that firmly establishes a first impression of electromagnetism and inspires a desire for further exploration, we can customize an exhibit specifically for you, jointly illuminating the first light of scientific discovery.
