Why is magnetism important for fusion power generation?

An understanding of electromagnetism is crucial for studying and developing fusion energy for power generation. For many fusion devices, magnets are vital for holding the hot fusion fuel--but it’s more than just that. Elecromagnetism is a fundamental building block of fusion science. Visiting the Royal Institution, where the British scientist Michael Faraday developed his theory of electromagnetism, Dr Melanie Windridge gives 3 reasons why we need to understand magnetism if we are to produce electricity
