Resonant wireless power transmission uses resonance to achieve higher efficiency than inductive coupling and is unaffected by non-magnetic obstacles. Efficiency can be optimized by adjusting coil size, number, or frequency. This apparatus includes transmitting and receiving coils, various loads (resistors, LEDs, fans), and media (wire mesh, aluminum plate). With ±90° coil rotation, it enables flexible and intuitive experiments that help learners understand electromagnetic field behavior in different media.
