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


Read this paragraph and choose the correct option from the provided answers:

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.

 Choices:

- gravitational

- kinetic

- thermal

- magnetic


A:
magnetic
