प्रश्न
What happens to the domains in a ferromagnetic material in the presence of external magnetic field?
Advertisements
उत्तर
- The domains having magnetic moments parallel to the field glow bigger in size.
- The other domains (not parallel to the field) are rotated so that they are aligned with the field.
