An electric dipole consists of two equal and opposite charges separated by a small distance. When a material becomes polarized, these dipoles align, creating a net electric dipole moment. This phenomenon is fundamental to understanding how materials interact with electric fields.<\/p>\n<p>The <strong>dielectric constant (\u03b5<sub>r<\/sub>)<\/strong>, a measure of a material\u2019s ability to store electric charge, is directly influenced by <strong>polarization in electromagnetism<\/strong>.
