Question 77Asked in DSSSB TGT Computer Science (Technical), 12 Sep 2025, Shift 2 (1:00 PM)

_________ materials are strongly attracted to regions of high magnetic field intensity

_________ materials are strongly attracted to regions of high magnetic field intensity due to _________.
  1. AFerromagnetic ; domains formed by an applied field
  2. BParamagnetic ; domains where dipoles align spontaneously
  3. CParamagnetic ; domains formed by an applied field
  4. DFerromagnetic ; domains where dipoles align spontaneously
Show answerHide answer

Correct answer: (D) Ferromagnetic ; domains where dipoles align spontaneously

Explanation

In ferromagnetic materials (iron, cobalt, nickel) atomic dipoles align spontaneously in small regions called domains. An external field grows and aligns these domains, so the material is strongly attracted.
