Nickel shows ferromagnetic property at room temperature. If the temperature is increased beyond Curie temperature, then it will show:

1. anti ferromagnetism
2. no magnetic property
3. diamagnetism
4. paramagnetism

Correct answer: paramagnetism

Solution

Above the Curie temperature, ferromagnetic materials like nickel lose their ferromagnetic properties and behave as paramagnetic materials due to the randomization of magnetic domains.
