NEET Physics Magnetic Properties of Materials MCQ Question
Which of the following statements about the magnetic properties of materials is correct?
Paramagnetic materials have permanent magnetic dipoles that align with external magnetic fields.
Diamagnetic materials exhibit a strong attraction to magnetic fields and have enhanced magnetization.
Ferromagnetic materials do not retain magnetization after the external field is removed.
The magnetic field inside a solenoid filled with a material of non-zero magnetization is less than the applied field B0.
Correct Answer
Detailed Explanation
Paramagnetic materials possess permanent magnetic dipole moments that can align in the presence of an external magnetic field, leading to net magnetization. This is highlighted in the context of how atomic dipole moments align in an external field.
