- History: The dynamo was developed in the 19th century, following the discovery of electromagnetic induction by Michael Faraday. The first dynamo was built by Hippolyte Pixii in 1832.
- Functionality: It converts mechanical energy into electrical energy by utilizing the principle of electromagnetic induction where a coil rotates within a magnetic field.
- Types: There are several types of dynamos including:
- Self-excited dynamo: Where the field magnet is excited by the current produced by the dynamo itself.
- Separately excited dynamo: Where an external source provides the current for the field magnet.
- Applications: Historically used for lighting, power supply in early vehicles, and in various industrial applications.
2. Dynamo in Computing and Data Storage
In the realm of computing, Dynamo can refer to:
- Amazon DynamoDB: A fully managed NoSQL database service provided by Amazon Web Services. It supports key-value and document data models, offering performance at any scale.
- Dynamo Project: A distributed key-value store system developed by Amazon to handle the shopping cart service in the early 2000s, which later influenced the development of DynamoDB.
Key Features of DynamoDB:
- Scalability and High Availability
- Flexible Data Model
- Automatic Scaling
- Backup and Restore
3. Dynamo in Popular Culture
Dynamo also appears in various forms of media and entertainment:
- Dynamo (Magician): The stage name of Steven Frayne, a British magician and illusionist known for his street magic and large-scale illusions.
