Oxygen is MAGNETIC?!

In this Physics Girl video, Dianna explores the fascinating behavior of liquid oxygen in a magnetic field at MIT. The demonstration showcases how liquid oxygen, a paramagnetic material, aligns with an external magnetic field, unlike other liquids. The video also explains the concepts of electromagnets, paramagnetism, and ferromagnetism, using iron to demonstrate the Curie point. The video concludes with a preview of future demonstrations and a thank you to the MIT technical services group.
