Define the following terms:Anisotropic solidFerromagnetic solid

Answer»
  1. Anisotropic solid: Solids which have different arrangement of particles in different directions such as crystalline solids are anisotropic solids. In these solids, physical properties like refractive index are different when measured along different directions in a same solid.
  2. Ferromagnetic solid: Solids which are attracted very strongly by a magnetic field are ferromagnetic solids e.g., iron, cobalt, nickel etc. Here, all domains (group of metal ions) orient in same direction of applied magnetic field to produce strong magnetic effect and this persist even when magnetic field is removed.
