How Does a Magneto Work in Charging Applications?
A magneto works in charging applications by generating electrical power through electromagnetic induction. It consists of a magnet, a coil of wire, and a rotating mechanism. When the magnet spins, it creates a changing magnetic field. This changing field induces an electric current in the wire according to Faraday’s law of electromagnetic induction.
The basic sequence begins with the engine or rotor that turns the magnet. As the magnet rotates, it passes by the wire coil. This movement generates a current in the coil. The produced current is alternating current (AC). An internal rectifier converts this AC into direct current (DC), which can charge a battery.
The connection between these steps is crucial. The rotation of the magnet initiates the entire process, allowing the creation of electricity. Without movement, there would be no change in the magnetic field, and thus no power generation.
