Camellia is performing an investigation in which she wraps a current carrying wire around an iron rod. She places the north pole of a bar magnet near the top of the rod. The magnet moves away from the rod can make it claims that a field exist between the rod, and the magnet, which argument best supports camellia claim. A. The current in the wire has created a magnetic field with its north pole at the top of the rod.B. The current wire has created a magnetic filled with south pole at the top of the rod.C. The current wire has created a gravitational field with his north pole at the top of the rod.D. The current wire has created a gravitational field with its south pole at the top of the rod.
The best argument to support Camellia's claim is option A. The current in the wire has created a magnetic field with its north pole at the top of the rod.
When a current-carrying wire is wrapped around an iron rod, it creates a magnetic field around the rod. According to the right-hand rule, the magnetic field lines are in the direction of the current in the wire. Since the north pole of the bar magnet moves away from the rod, it suggests that there is a repulsive force between the north pole of the magnet and the north pole of the magnetic field created by the current in the wire. Therefore, option A is the most likely explanation for Camellia's claim.
