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

Options

A. paramagnetic
B. anti-ferromagnetism
C. diamagnetism
D. no magnetic property

Answer

A

Explanation

When temperature increases beyond

Curie temperature, the disorder of the magnetic moments of the material increses, hence alignment moment are distrubed which caused material to behave as paramagnetic
