"To Future Scientists" series is a science video published on the official YouTube channel of the National Institute for Materials Science (NIMS), a Japanese public research organization. It is produced to promote NIMS and to widely share the fascination and appeal of materials research. The theme of #19 is the "Halbach array." By simply changing the arrangement of magnets, the magnetic force changes, revealing the profound nature of magnets—something familiar, yet not widely known.

Description: The “To Future Scientists” series is a science video series available on the official YouTube channel of the National Institute for Materials Science (NIMS), a public research institution in Japan. Along with promoting NIMS, it is created to broadly convey the fascination and appeal of materials science research. The theme of #18 is “The Shadow of Infrared Light.” Infrared light is an invisible form of light that truly exists all around us, yet we are usually unaware of it. Using a distinctive method, this work reveals the power of infrared light. Though it is a simple experiment, it also symbolizes how changing the way we see the world can lead to new discoveries and ideas.

It was created to promote NIMS and to widely share the fascination and appeal of materials science research. The theme of #17 is the “Curie engine.” Materials such as iron that are attracted to magnets stop being attracted when they reach a specific temperature (the Curie temperature), and become attracted to magnets again as the temperature drops. Using this property, an experimental device was designed to reveal its intriguing behavior through video.
