Wireless Power Supply
★Exhibit Content: Wireless Charging ★Interaction: Electromechanical Interaction ★Operation: 1. Press the "Principle Demonstration" button, move the slider left and right, and observe the changes as the slider approaches the coil; 2. Press the "Car Charging" button and observe the changes in the car; 3. Press the "Phone Charging" button, place a phone with wireless charging capability on the tray, and observe the changes in the phone. ★Exhibit Description: The exhibit consists of a wireless charging principle demonstration device, a car charging demonstration device, and a phone charging device. Visitors can switch functions via buttons to experience the convenience of wireless charging. ★Scientific Principle: Wireless charging, also known as inductive charging or non-contact inductive charging, utilizes near-field induction, i.e., inductive coupling, where a power supply device (charger) transmits energy to a device that uses the received energy to charge the battery and simultaneously power its own operation. Since energy is transmitted between the charger and the device via inductive coupling without wire connection, both the charger and the device can be designed with no exposed conductive contacts.

★Exhibit Content: Wireless Power Supply Principle, Electromagnetic Induction and Magnetic Resonance Wireless Power Transmission Technology ★Interaction: Electromechanical Interaction ★Operation: 1. Press the left start button, slide the receiving coil, adjust the distance from the transmitting end, and observe the brightness change of the light; 2. Insert the phone charging cable into the phone charging port, press the right button, place the small disc on the receiving pad, and observe the charging status of the phone. ★Exhibit Description: This exhibit is a recommended exhibit from the PopsciCat Exhibit Store. It consists of a blue and white console, a magnetic resonance wireless power transmission demonstration module, and a phone wireless charging experience area. On the left side of the tabletop, two sets of transparent disc-shaped coils are mounted, serving as the transmitting and receiving ends, connected by stainless steel dual rails. The receiving end can slide along the rails to adjust the distance, and the coils have built-in LED indicators. On the right side of the tabletop, there is a phone placement area and a circular wireless charging transmitting pad, accompanied by a portable receiving small disc and charging cable. Through two interactive experiments, visitors can observe the effect of coil distance on transmission efficiency and the actual effect of phone wireless charging, intuitively understand the working process of wireless power transmission technology, and transform abstract electromagnetic resonance theory into an operable and observable science popularization experience. ★Scientific Principle: Wireless power supply is a technology that transmits electricity without any wires, using electromagnetic induction, electromagnetic resonance, or radio waves. Among these, electromagnetic resonance is currently the most researched power transmission method. Electromagnetic resonance uses coils and capacitors to form a resonant circuit between the charger and the device. When the frequencies of the transmitting and receiving ends match, resonance occurs, achieving efficient wireless power transmission. The closer the coils and the higher the coupling degree, the higher the transmission efficiency, and the brightness of the indicator light changes accordingly; phone wireless charging is also based on near-field electromagnetic induction, coupling the power from the transmitting pad to the receiving end to complete charging.
