JEE Mains · Physics · STD 12 - 5. Magnetism and matter
A soft ferromagnetic material is placed in an external magnetic field. The magnetic domains:
- A increase in size but no change in orientation.
- B have no relation with external magnetic field.
- C decrease in size and changes orientation.
- D may increase or decrease in size and change its orientation.
Answer & Solution
Correct Answer
(D) may increase or decrease in size and change its orientation.
Step-by-step Solution
Detailed explanation
Soft ferromagnetic materials are materials which can be easily magnetised and demagnetised by external magnetic field. When external field is applied, the domains experiences a net torque hence change its orientation.
