Praxis 5025 Practice Question
Which of the following concepts of magnetism is best illustrated by the diagram, which shows a steel nail in contact with both a magnet and a paper clip?
Correct Answer: D
Rationale: The diagram illustrates how a steel nail, when in contact with a magnet, becomes magnetized itself, demonstrating the concept of induced magnetism. This process shows that certain materials can gain magnetic properties when exposed to a magnetic field.
Option A is incorrect as it refers to electromagnetism, which involves electric current, not applicable here. Option B, while true about magnets, does not relate to the interaction shown in the diagram. Option C discusses the attraction or repulsion between magnets, which is not the focus of the image. Thus, the best representation of the concept illustrated is the induction of magnetism in the steel nail.
