6. A student wrapped 30 cm of insulated wire around the middle of an iron rod, leaving ends A and B exposed. She connected the non-insulated ends of the wire to a battery. She brought a permanent magnet near end B of the iron rod, and it was repelled. The picture to the right shows the students experiment. Which best explains why the permanent magnet was repelled? a. The wire became magnetized when an electric current flowed through it, and end B of the iron rod must have shared the same pole as the permanent magnet. b. The iron rod became magnetized when it was wrapped Insulated wire End A by the wire, and end B of the iron rod must have had a Permanent Iron Rod magnet pole opposite of the permanent magnet pole. C. The iron rod became magnetized when it was wrapped by the wire, and end B of the iron rod must have shared the same pole as the permanent magnet. Battery d. The wire became magnetized when an electric current flowed through it, and end B must have had a pole opposite that of the permanent magnet. End B
