Question
A student wound 30 cm of insulated wire around the center of an iron rod, with exposed ends labeled as A and B. The non-insulated wire ends were connected to a battery. When the student approached end B of the iron rod with a permanent magnet, it exhibited repulsion. The image illustrates the student's experiment.
What provides the most accurate explanation for the repulsion of the permanent magnet?
(1 point)
Responses
The iron rod gained magnetization as the wire wound around it, and end B of the iron rod likely had the same pole as the permanent magnet, leading to repulsion.
The iron rod gained magnetization as the wire wound around it, and end B of the iron rod likely had the same pole as the permanent magnet, leading to repulsion.
When an electric current passed through the wire, it became magnetized, and end B of the iron rod likely possessed the same pole as the permanent magnet, leading to repulsion.
When an electric current passed through the wire, it became magnetized, and end B of the iron rod likely possessed the same pole as the permanent magnet, leading to repulsion.
The wire acquired magnetization when an electric current passed through it, and end B presumably had a pole opposite to that of the permanent magnet, resulting in repulsion.
The wire acquired magnetization when an electric current passed through it, and end B presumably had a pole opposite to that of the permanent magnet, resulting in repulsion.
The iron rod acquired magnetism when encircled by the wire, and end B of the iron rod presumably possessed a pole opposite to that of the permanent magnet, resulting in repulsion.
The iron rod acquired magnetism when encircled by the wire, and end B of the iron rod presumably possessed a pole opposite to that of the permanent magnet, resulting in repulsion.

The most accurate explanation for the repulsion of the permanent magnet in this scenario is:
**When an electric current passed through the wire, it became magnetized, and end B of the iron rod likely possessed the same pole as the permanent magnet, leading to repulsion.**
This statement correctly identifies how the passing current magnetizes the wire, which in turn magnetizes the iron rod, and suggests that the similar poles of the magnet and the rod result in the observed repulsion.
**When an electric current passed through the wire, it became magnetized, and end B of the iron rod likely possessed the same pole as the permanent magnet, leading to repulsion.**
