Ferromagnetism | MCQs

Explanation

Ferromagnetic materials are those that can be magnetized and retain their magnetization even after the external magnetic field is removed.

These materials have a high magnetic permeability and strong interactions between magnetic moments, which align in the same direction.

Explanation

Explanation

Ferromagnetic materials are those that can retain their magnetization even after an external magnetic field is removed.

They are strongly attracted to magnets. Iron, nickel, and cobalt are all ferromagnetic materials.

Barium, on the other hand, is not ferromagnetic

It is classified as a diamagnetic material, meaning it weakly repels magnetic fields. 

Explanation

• Iron is a ferromagnetic material, which means it is strongly attracted to magnets.
• Therefore, an iron kettle will be attracted to a magnet.

Explanation

Ferromagnetic materials (such as iron, cobalt, and nickel) have a strong attraction to magnetic fields and can retain their magnetism even after the external magnetic field is removed.

This property makes them ideal for making permanent magnets.

• Diamagnetic materials are repelled by magnetic fields and cannot retain magnetism.

• Paramagnetic materials are weakly attracted to magnetic fields but do not retain magnetism after the external field is removed.
