Question 108

Magnetic force can induce magnetism in particular materials.

The diagram illustrates how a steel nail, when in contact with a magnet, can become magnetized itself due to the influence of the magnetic force. This process demonstrates that certain materials can exhibit magnetism as a result of exposure to a magnetic field.

A) Magnetic force causes the nail to act as an electromagnet.

This option is incorrect because an electromagnet is created through the flow of electric current, which is not depicted in the context of the diagram. The nail's magnetism in the scenario is induced by the magnetic field of the magnet, not by electric current.

B) Magnets have a magnetic north pole and a magnetic south pole.

While it is true that magnets possess north and south poles, this option does not accurately reflect the main concept illustrated by the diagram. The focus of the diagram is on how magnetism is induced in the nail rather than the properties of the magnet itself.

C) Magnets can either attract or repel each other.

This statement is also true regarding the behavior of magnets; however, it does not address the specific interaction shown in the diagram. The primary concept illustrated is about the induction of magnetism in the steel nail, rather than the attraction or repulsion between magnets.

D) Magnetic force can induce magnetism in particular materials.

This option is correct as it directly relates to the diagram. The presence of the magnet induces a magnetic effect in the steel nail, demonstrating how certain ferromagnetic materials can become magnetized when exposed to a magnetic field.

Conclusion

The correct answer, D, clearly illustrates the phenomenon of magnetic induction, which is the key concept demonstrated in the diagram with the steel nail, magnet, and paper clip. Options A, B, and C, while they contain truths about magnetism, do not accurately capture the specific interaction taking place as shown in the diagram, thus failing to address the core concept of induced magnetism.
