Answer the following question given this paragraph: 

Electromagnetism is magnetism produced by an electric current. When electric current flows through a wire, it creates a magnetic field that surrounds the wire in circles. You can see this in the diagram below. Note that electric current is conventionally shown moving from positive to negative electric potential, as in this diagram. However, electrons in current actually flow in the opposite direction, from negative to positive potential.


Q: When electric current flows through a wire, it creates what type of field that surrounds the wire in circles?


A:
magnetic
