What happens to the domains in this iron nail when the south pole of a magnet approaches it from the top?
Understand the Problem
The question is asking what happens to the magnetic domains in an iron nail when the south pole of a magnet comes near it from above. This involves understanding the behavior of magnetic domains in ferromagnetic materials in response to an external magnetic field.
Answer
D. All the arrows align to point down.
The final answer is D. All the arrows align to point down.
Answer for screen readers
The final answer is D. All the arrows align to point down.
More Information
When the south pole of a magnet approaches an iron nail, the magnetic domains in the nail align themselves with the external magnetic field. Since the south pole is approaching from the top, this causes the domains to align downward.
Tips
A common mistake is misjudging the direction of domain alignment due to the position of the magnet. Ensure correct interpretation of magnetic influence.
