DIY Electromagnetism Experiment Kit STEM Educational Levitation Technology Primary School Electricity Science Learning Materials

Electromagnetic Experiment with Space Separation and Electricity Extraction DIY Technology Elementary School Electrical Scienceworking principleEnergy can be effectively transmitted between two objects with the same resonance frequency, while the interaction between objects with different frequencies is weakSchematic diagram of wireless chargerBy coupling energy through two inductive coils, the current output by the secondary coil is converted into direct current through the receiving and converting circuit to supply power to the LED lampWireless charging technology utilizes magnetic resonance to transmit electrical energy in the electric and magnetic fields between the charger and the device, while coils and capacitors form resonance between the charger and the device.Notes:Please allow 1-2cm error due to manual measurement.Due to the difference between different monitors, the picture may not reflect the actual color of the item, hope you can understand.
