A soft ferromagnetic material is placed in an external magnetic field,the magnetic domains. A) Decrease in size and changes in orientation B) May increases or decreases in size and changes its orientation C) Have no-relation with external magnetic field D) Increased in size but no change in orientation
Question
A soft ferromagnetic material is placed in an external magnetic field,the magnetic domains. A) Decrease in size and changes in orientation B) May increases or decreases in size and changes its orientation C) Have no-relation with external magnetic field D) Increased in size but no change in orientation
Solution
When a soft ferromagnetic material is placed in an external magnetic field, the magnetic domains align themselves with the external field. This means that they change their orientation to match the direction of the external field. Therefore, the correct answer is B) May increases or decreases in size and changes its orientation. The size of the domains can either increase or decrease depending on the strength and direction of the external field.
