If a ferromagnetic material is inserted in a current carrying solenoid, the magnetic field of solenoid
Correct answer: A. Largely increases
- A. Largely increases
- B. Slightly increases
- C. Largely decreases
- D. Slightly decreases
Explanation
Inserting a ferromagnetic material into a current-carrying solenoid largely increases the magnetic field inside. This is because ferromagnetic materials, like iron, have a high magnetic permeability, which means they can become highly magnetised when exposed to an external magnetic field. This alignment of magnetic domains within the ferromagnetic material greatly enhances the overall magnetic field produced by the solenoid. The incorrect options either misrepresent the magnitude of this enhancement or wrongly suggest a decrease in the magnetic field, which does not occur with ferromagnetic materials.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
