Alab group has been tasked with conducting an experiment to see if the electric current flowing through a wire has any effect on a magnetic compass. The group sets up a straight length of wire on the surface of their lab bench and then connects the two ends to a battery to get current to flow through the wire. Next, the group sets the compass flat on the table at three different points, as seen in the diagram below: Point A Point b Point C TABLE (lop with) The needle of the compass was unaffected at every point. The lab group concludes that the electric current flowing through a wire has no effect on a magnetic compass . Are the results of their experiment enough to validate this claim? No, because they didn't try the experiment with multiple compasses O No, because they didn't test the location of the compass at every point around the wire )Yes, because they only changed one variable at a time O Yes, because they used the compass to test the effect in several different locations along the wire
