Generator Effect - GCSE Physics Definition

The 'Generator Effect' refers to the phenomenon where an electrical conductor moving through a magnetic field, or a magnetic field moving around a conductor, induces a voltage across the conductor. This occurs due to electromagnetic induction and is a fundamental principle in the operation of devices like dynamos and alternators. For GCSE Physics students, it's essential to understand that the voltage generated can cause a current to flow if the conductor forms a complete circuit. The magnitude of the induced voltage depends on factors such as the speed of movement, the strength of the magnetic field, and the number of coils in the conductor. The generator effect is crucial for converting mechanical energy into electrical energy across various power generation applications.
