Question

Which of the following is/are a ferromagnetic material ?

• A. Nickel
• B. Copper
• C. Tungsten
• D. Aluminium

Answer 1

Answer:

A. Nickel

Ferromagnetic materials exhibit permanent magnetism and attractive powers. Nickel, Iron, Cobalt, and Alloys are examples of ferromagnetic materials. Copper, Tungsten, and Aluminium are not ferromagnetic. Ferrimagnetism is another magnetic behavior where the net magnetic moment is achieved due to partial cancellation between ions with different magnetic moments.
