Complete the diagram by: (a) labeling and colour coding the electric and magnetic field lines and (b) showing the direction of all the field lines and current O О О О 2. Reason. How do the directions of the electric and magnetic field lines compare in this region of space? О wire 3. Explain. A positive test charge is placed at rest in this region of space. In this investigation, we will ignore the effects of the magnetic field since they are relatively small. What will happen to the positive charge which is initially is at rest? Explain and draw vectors representing any forces. Below is a third diagram showing the same region of space as above. But for this example, we have switched the polarity of the power supply, reversing the positive and negative terminals shown in the first diagram.
