Magnetic Properties of Matter: Practice Problem & Solution

32. Above Curie temperature: (2006)
A ferromagnetic substance becomes paramagnetic
A paramagnetic substance becomes diamagnetic
A diamagnetic substance becomes paramagnetic
A paramagnetic substance becomes ferromagnetic

Solution Explained:

To solve this problem, we apply the core principles of Magnetic Properties of Matter. Understanding the underlying formula is key to arriving at the correct answer below:

At temperatures higher than the Curie temperature, spontaneous magnetization in ferromagnetic materials vanishes and the substance transforms into a paramagnetic material obeying Curie-Weiss law.
