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.

What is the significance of liquid oxygen in the demonstration?

What happens to the liquid oxygen when the electricity is turned off?

Describe the process of how electromagnets are created according to the text.

Explain the concept of paramagnetism as it relates to liquid oxygen.

How does the behavior of iron differ from that of liquid oxygen in a magnetic field?

What is the curie point and how does it affect the behavior of iron in the demonstration?
