An object made of which material is likely to be attracted to a magnet?

• A. nitrogen
• B. nickel
• C. paper
• D. plastic

Answer: (B)

Nickel is a ferromagnetic material, meaning it has magnetic properties that allow it to be attracted to magnets. When exposed to a magnetic field, the domains within nickel can align with that field, resulting in a net attraction. This characteristic is why nickel is often used in various applications where magnetic properties are needed, such as in certain types of metal alloys or even in coins.

In contrast, nitrogen is a gas and does not have magnetic properties, while paper and plastic are non-metallic materials that do not exhibit magnetism. Their atomic structure does not allow for any magnetic alignment, which is why they will not be attracted to a magnet. Thus, nickel is the only option listed that will respond to a magnetic field, confirming its attraction to magnets.
