How do wireless chargers work?

Electromagnetic induction
This is how the most common wireless chargers work. It uses the principle of electromagnetic induction to generate current through the electromagnetic induction between the primary and secondary coils, .parts for phones , thereby realizing the transfer of energy in space.


radio waves
Radio waves are a relatively mature wireless charging method for wireless chargers at this stage. It works by capturing radio waves in space with tiny, highly efficient receiving circuits and then converting electromagnetic energy into stable electrical energy.


Electromagnetic resonance
It's a wireless charging technology that's still in development, and Intel's engineers say the next goal will be to use it to charge modified laptops. However, for this to happen, the interference and effects of electromagnetic fields on other components in the computer also need to be addressed.
