magnetic fields
Understanding the Answer
Let's break down why this is correct
An insulator keeps its electrons bound to atoms, but the electric field pulls the electrons a little from the nuclei. Other options are incorrect because Conductors let electrons move freely, so the field mainly pushes charges to the surface, not inside; Insulators lack free electrons that can travel through the material, so no free charges are produced.

Definition
Electric field induction occurs in insulators, creating dipoles due to the rearrangement of electrons when subjected to an external electric field. This phenomenon leads to the polarization of insulators, forming layers of induced charges. Understanding electric field induction is essential in studying dielectrics and their impact on electric fields.
