Question 108

Magnetic force can induce magnetism in particular materials.

The diagram illustrates how a steel nail, when in contact with a magnet, becomes magnetized itself through magnetic induction. This demonstrates the concept that certain materials can exhibit magnetism when influenced by an external magnetic field.

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

This option is incorrect because an electromagnet is created by electric current flowing through a coil, not by the magnetic force of a magnet acting on a ferromagnetic material. The steel nail in the diagram does not require electric current to become magnetized.

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

While it is true that magnets possess both a north and south pole, this option does not relate directly to the interaction shown in the diagram. The focus of the diagram is on the induction of magnetism in the nail, rather than the properties of the magnet itself.

C) Magnets can either attract or repel each other.

This statement is valid for magnet interactions but does not pertain to the situation depicted in the diagram. The emphasis is on the magnetic induction effect on 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 accurately describes the process occurring in the diagram. The steel nail becomes magnetized due to the magnetic field of the magnet, showcasing how certain materials can gain magnetic properties through induction.

Conclusion

The correct answer, option D, effectively captures the principle of magnetic induction, which is exemplified by the steel nail becoming magnetized when in contact with the magnet. The other options either misrepresent the concept or fail to address the phenomenon illustrated in the diagram, reinforcing why D is the most accurate choice.
