4. Which of the following best describes what happens when two magnets repel each other?
Answer: B
Two magnets repel each other, causing the objects to be pushed away from one another.
When two magnets repel each other, they exert a force that pushes them apart, demonstrating the fundamental principles of magnetism.
A) The objects are pulled toward one another.
This option is incorrect because it describes attraction rather than repulsion. When two like poles of magnets are brought close, they do not pull towards each other; instead, they push away, illustrating the nature of magnetic forces.
B) The objects are pushed away from one another.
This option is correct as it accurately depicts the behavior of two magnets with like poles facing each other. The repelling force causes the magnets to move away from one another.
C) An electric spark jumps from one object to another.
This option is incorrect because the interaction between two repelling magnets does not involve any electric discharge or spark. The phenomenon of electric sparks is unrelated to the magnetic forces at play during repulsion.
D) Nothing happens until the objects are touched.
This option is also incorrect. Even before physical contact, the magnets exert a force on each other that results in repulsion, indicating that action occurs prior to touching.
Conclusion
The correct answer, option B, accurately describes the repulsion between two magnets, which is a fundamental property of magnetic forces. All other options misinterpret the nature of magnetism, either by confusing attraction with repulsion or incorrectly stating that no action occurs until contact is made.
