Question
Materials with this property have a relative permeability slightly greater than 1. For 10 points each:
[10m] Name this property possessed by materials with unpaired electrons. Heating up a material beyond the Curie point corresponds with a phase transition to this property.
ANSWER: paramagnetism [prompt on magnetism]
[10e] Materials with this property become paramagnetic when heated beyond the Curie point. This form of permanent magnetism is exhibited by iron, nickel, and cobalt.
ANSWER: ferromagnetism
[10h] This scientist developed a function equal to coth [co-th] x minus one over x to model the statistical behavior of paramagnetic materials. This scientist also developed an equation to model the movement of particles in Brownian motion.
ANSWER: Paul Langevin [accept Langevin equation or Langevin function]
