Electromagnetic Field Generation

The animation shows how static electric field lines from a positive point charge produce a radiation field if the charge oscillates.  Notice how the electric field lines form waves that move away from the charge. 

Question 1

 In what direction is the radiation a maximum?

  1. The radiation is a maximum perpendicular to the direction of oscillation.
  2. The radiation is a maximum along the direction of oscillation.
  3. The radiation is uniform in all directions.

Question 2

What is the direction of the magnetic field associated with the waves in the plane and immediately to the right of the oscillating charge?

  1. The magnetic field will always point in the same direction as the electric field.
  2. The magnetic field will point to the right.
  3. The magnetic field will alternate between pointing upward and downward.
  4. The magnetic field will alternate between pointing into and out of the screen.
  5. The magnetic field will alternately wrap clockwise and counterclockwise.
