One of the fancy method people used to charge their phone is using wireless charging. Do you know how wireless charging work? One type of wireless charging is using a method named electromagnetic induction. There are two induction coils in both the charging pad and the mobile phone. When the charging pad is plugged in, Alternative current (AC) flows through the induction coil of the charging pad. This creates an electromagnetic field. When the secondary coil in the smartphone comes near the generated electromagnetic field it creates a current. This current is used to charge the phone.
