{"version":"1.0","type":"link","title":"Polarization density - Newikis","description":"In classical electromagnetism, polarization density (or electric polarization, or simply polarization) is the vector field that expresses the volumetric density of permanent or induced electric dipole moments in a dielectric material. When a dielectric is placed in an external electric field, its…","provider_name":"Newikis","provider_url":"https://newikis.com","cache_age":86400,"thumbnail_url":"https://thumb.wikimedia.org/wikipedia/commons/thumb/0/0d/VFPt_Solenoid_correct2.svg/1280px-VFPt_Solenoid_correct2.svg.png","thumbnail_width":1280,"thumbnail_height":522}
