Question

Which of the following is ferromagnetic:

Hint:

Ferromagnetic materials are often transition metals with unpaired electrons that align to create a strong magnetic field. Examples include iron, cobalt, and nickel.

Answer 1

Ferromagnetism refers to the property of certain materials to form permanent magnets or be attracted to magnets. Among the given options: \begin{itemize} Zinc (Zn): It is a diamagnetic material and does not exhibit ferromagnetic properties. Copper (Cu): Copper is also diamagnetic, showing no ferromagnetic behavior. Manganese (Mn): Manganese is paramagnetic in its pure state but not ferromagnetic. Chromium (Cr): Chromium is typically antiferromagnetic at room temperature, but certain alloys can exhibit ferromagnetic behavior. \end{itemize} The correct answer as ferromagnetic is Chromium, particularly in specific alloyed forms.
