Which statement about lines of magnetic force is best supported, according to the material?

• A. They are straight lines only
• B. They can bend around objects
• C. They do not interact with magnets
• D. They can be described by rubber-band analogies that stretch

Answer: (D)

Lines of magnetic force are a visualization of how the magnetic field behaves in space. They behave like flexible elastic strings stretched between poles, bending around objects and curving to follow the shape of the field created by magnets and materials. The rubber-band analogy fits well because a line will bend when the surrounding magnetic forces change direction, and its tension (or density) increases where the field is stronger. This mental model helps you predict how lines will arrange themselves as geometry changes, which is why describing them with rubber-band analogies that stretch is the best-supported idea.
