Noel is trying to understand the relationship between electron flow and the polarity of an electromagnet. He wants to test the electromagnet he created, shown in the photograph. First, Noel needs to know which direction electrons flow through the copper wire. Which statement about the flow of electrons is correct?

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm). (e
