When magnets meet liquid nitrogen... | The Royal Society

This event is part of the Royal Society's Summer Science Exhibition 2024.
We all know that different materials have unique properties. For instance, water can transform into ice, liquid, or steam based on the temperature. These transformations are known as phase transitions.
In this demonstration, Dr Gunnar Möller and Megan Bell will reveal captivating phase transitions in materials like magnets and high-temperature superconductors. They'll use liquid nitrogen to cool these materials to astonishingly low temperatures, creating mesmerizing effects! Discover how superconductors float above powerful magnets, all due to the wonders of quantum mechanics.
Dr. Gunnar Möller is senior research fellow at the University of Kent's School of Physics and Astronomy and has recently completed a Royal Society University Research Fellowship. He uses powerful computers and the mind-bending science of quantum mechanics to create models that predict the behaviour of materials like superconductors and topological materials. These materials have incredible properties, like floating above magnets or conducting electricity without any resistance. Gunnar's work helps us understand and harness these exotic states of matter.
Megan Bell is a STEM Outreach Officer at the University of Kent, where she leads the exciting STEM Outreach & Widening Participation program. She travels to schools and colleges across Kent and Medway, inspiring students to reach for the stars in science, technology, engineering, and math. Megan's mission is to help students achieve their dreams and realize their full potential in these exciting fields.
The Royal Society is a Fellowship of many of the world's most eminent scientists and is the oldest scientific academy in continuous existence.

This lecture is for children. Balloon animals. Not worth watching for grownups.
