Click here to see movie

PIRA Classification: 5G50.25

Description: Dysprosium (Z=66) is normally non-magnetic at room temperature (as can be demonstrated by bring a magnet near it). When the metal is cooled with liquid nitrogen (bringing it below its Curie point), it becomes ferromagnetic. As it warms, it becomes non-magnetic again.

Special Instructions: None

Condition: Good

Setup time: 2 minutes

Safety Issues: Liquid nitrogen is cold!
