If clockwise current (1) flows through a metal ring as viewed from the top (ring is placed in the plane of paper/screen), what is the direction of magnetic field produced inside the right by the current in the clockwise direction as shown? A. To the top of the screen (upward) B. To the bottom of the screen (downward) c. Out of the screen D. Into the screen E. There is no magnetic field.

List the ways in which magnetic field lines and electric field lines the similar. For example, the field direction is tangent to the line at any point in space. Also list the ways in which they differ. For example, electric force is parallel to electric field lines, whereas magnetic force on moving charges is perpendicular to magnetic field lines.
