Α farmer has earned a lot of money by turning old bicycle wheels into powerful generators.
A generator is a machine that turns motion into electricity using a principle called electromagnetic induction.
When electric current flows through a wire, it creates a magnetic field around it. You might wonder why your phone charger cable doesn’t stick to metal. This is because the current is very small, so the magnetic field is too weak to notice. But with stronger currents, the magnetic field becomes powerful enough to do things like lift heavy metal using industrial cranes.
This process also works in reverse. If you move a magnetic field near a wire, it creates an electric current in that wire. “Moving” can mean physically moving a magnet or simply turning the magnetic field on and off repeatedly.
So, by spinning a magnet near a wire, like with a rotating bicycle wheel, you can generate electricity.
Why it matters:
This shows how simple, low-cost materials can be turned into useful energy solutions, especially in rural areas. It’s a practical example of recycling and renewable energy coming together to create income and power where it’s needed most.
