What does electric current measure?
A. How quickly electrical energy moves in a circuit
B. how frequently electrical energy moves in a circuit
C. how much electrical energy moves in a circuit**
D. how well electrical energy moves in a circuit
How is a magnetic field produced?
A. when an object has an electric charge
B. when electrons move through a circuit
C. when an electromagnet field interacts with a magnet
D. when a current runs through a conductor**
Which statement best describes how an electromagnet motor works?
A. Electrons are moved through a magnet, creating a current. That current interacts with a circuit, moving the conductor in the orientation of the field.**
B. Electrons are moved through a circuit, creating a current. That current interacts with a magnet, moving the conductor in the orientation of the field.
C. Electrons are moved through a magnet, creating a circuit. That circuit interacts with a current, moving the conductor in the orientation of the field.
