Sanzida conducted an experiment that required a wire carrying a current to be wrapped around a metal core. When she placed the South Pole of a bar magnet near the top of the metal rod, she observed the magnet move toward the rod. Which conclusion can Sanzida draw from this experiment?
A) the current in the wire has created a gravitational field with its South Pole at the top of the rod
B) the current in the wire has created a magnetic field with its South Pole at the top of the rod.
C) the current in the wire has created a magnetic field with its North Pole at the top of the rod.
D) The current in the wire has created a gravitational field with its North Pole at the top of the rod
