EM Waves - Oscillating Charge

The animation shows how static electric field lines from a positive point charge produce a radiation field if the charge is caused to oscillate.  Initially the charge is not moving.  Restart

Notice how the electric field lines form waves that move away from the charge when the charge is oscillating.  Start Charge Oscillating  

a) What is the direction of the magnetic field associated with the waves to the right of the charge?  

b) In what direction is the radiation a maximum?
