Which of the following magnetic material is temperature dependent?
Correct answer: B. Paramagnetism
- A. Diamagnetism
- B. Paramagnetism
- C. Feromagnetism
- D. None of these
Explanation
Paramagnetism depends upon temperature. Above the Curie temperature, the material becomes paramagnetic. Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field. Due to their spin, unpaired electrons have a magnetic dipole moment and act like tiny magnets.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
