But what about wireless charging?
2. What Is the Concept of Wireless Charging?
Inductive Charging, Commonly Known as Wireless Charging, Operates on the Same Principle as Induction Cooktops: Electromagnetic Induction
Electromagnetic Induction Results from Generating Electric Current through a Conductor Placed in a Changing Magnetic Field or a Conductor Moving in a Static Magnetic Field
3. How Is Wireless Charging Structured and How Does It Work?
An induction charging system consists of two primary induction coils. One is placed within the charging base and is responsible for generating an alternating current from within. The other part is integrated into mobile devices such as smartphones, tablets, etc. These coils can take the form of a flat panel attached to the phone, an embedded circuit inside the phone, or a replacement battery cover with a built-in charging coil. Together, these two coils create an electrical transformer.
When power is supplied to the charging base, an alternating current flows through and generates an electromagnetic field (a changing magnetic field) around the primary coil. When the secondary coil (the receiving coil placed in smartphones) comes close enough, a current is induced in the coil. The alternating current flowing through the coil in the smartphone is converted into direct current by receiver circuits. The direct current generated in this manner is ultimately used to charge the smartphone battery.
