5) Magnetic field lines inside the solenoid shown are: (a) clockwise circles as one looks down the axis from the top of the page (b) counterclockwise circles as one looks down the axis from the top of the page (c) toward the top of the page (d) toward the bottom of the page (e) in no direction since B = 0 6) As an externally generated magnetic field through a certain conducting loop increases in magnitude, the field produced at points inside the loop by the current induced in the loop must be (a) increasing in magnitude (b) decreasing in magnitude (c) in the same direction as the applied field (d) directed opposite to the applied field (e) perpendicular to the applied field 7) The time averaged energy in a sinusoidal electromagnetic wave is: (a) overwhelmingly electrical. (b) slightly more electrical than magnetic (c) equally divided between the electric and magnetic fields. (d) slightly more magnetic than electrical. (e) overwhelmingly magnetic. 8) As used in the laws of reflection and refraction, the "normal" direction is.. (a) any convenient direction (b) tangent to the interface (c) along the incident ray (d) perpendicular to the electric field vector of the light (e) perpendicular to the interface
