Temperature and Magnetism: Meissner Effect using Liquid Nitrogen

Photo Shows the Demonstration Used by the University of Texas at Austin.

Instructions / Notes:

• Demo Staff: Pick up the liquid nitrogen early or the day before the demo.
• A superconductor disc is placed in a styrofoam dish and liquid nitrogen is added to the dish by the instructor.
• Once the disc is covered with LN₂, a small magnet is placed on top and within a several seconds it will begin to levitate.
• This demonstration is best displayed with the use of a goose neck television camera, which has a macro capability.
• In lieu of the above goose neck television camera, a small camera with a video mode and an HDMI output may be used to show the demo.
• Whichever camera is used, it must be connected to the classroom A/V system.
