When a dielectric material is kept in an external electric field, which one of the following phenomena may be realized ?

This questions was previously asked in

EPFO AO EO 2021

Magnetization

Polarization

Photoionization

Circularization

- Option 1: Magnetization

This refers to the alignment of magnetic dipoles in a material when exposed to a magnetic field, not an electric field.

- Option 2: Polarization

This is the correct answer. Dielectric materials develop electric dipoles aligned with the applied electric field, causing polarization.

- Option 3: Photoionization

This happens when light (photons) ionizes atoms or molecules. It is unrelated to electric fields.

- Option 4: Circularization

This is not a recognized physics phenomenon related to dielectric materials or electric fields.
