  "term": "Permeability",
  "field": "Chemistry",
  "definition": "A measure of the ability of a material to allow the passage of a fluid or a magnetic field through it. In the context of materials, it quantifies the ease with which a substance can diffuse through a membrane or porous medium. For magnetic fields, it describes how a material responds to and modifies the field within it, measured in henries per meter (H/m).",
