What happens to the magnetic domains within a material when it is exposed to an external magnetic field?
What happens to the magnetic domains within a material when it is exposed to an external magnetic field?
- They become smaller and more randomly oriented.
- They remain unchanged and unaffected by the external field.
- They align themselves with the external magnetic field. (correct)
