Wireless chargers use magnetism to move power from one place to another, like a game of telephone, but with electricity.
Imagine your phone is like a friend who wants to get a message (power) from another friend across the room. Instead of passing notes, they use magnets. One friend has a magnet that shakes back and forth really fast, this makes the other friend’s magnet shake too, even though they’re not touching.
This shaking is like electricity moving through your phone. The faster the magnets shake, the more power gets sent to your phone, just like how a louder voice carries farther in a game of telephone.
How it works step by step
- The wireless charger has a special coil, think of it like a spring, that uses electricity to create magnetism.
- Your phone also has a similar coil inside it.
- When you place your phone on the charger, the magnet from the charger makes the magnet in your phone shake.
- This shaking creates electricity inside your phone, which charges the battery.
It’s like giving your phone a little electric hug, no wires needed! Wireless chargers use magnetism to move power from one place to another, like a game of telephone, but with electricity.

Examples
- A wireless charger uses invisible magnetic fields to move energy from the charger to your phone.
- It's like magic, no wires needed, just a little science.
- Your phone is like a magnet that can receive power without touching anything.
