The video tutorial explains the generator effect, which induces a potential difference and current in a conductor within a magnetic field. It covers methods to increase induced current, such as increasing wire turns, magnetic field strength, and speed. The Dynamo is introduced as a generator for direct current, with a focus on the split ring commutator's role in maintaining current direction. The video also analyzes current variation graphs and discusses factors affecting induced current, including rotational frequency, magnet strength, and coil turns.
