Figure P30.6 shows an increasing magnetic field and the electric field that accompanies it according to Faraday's law. If the magnetic field is increasing at an increasing rate, 

\((a)\) is the electric field magnitude constant, increasing, or decreasing?

(b) Does the behavior of the electric field produce an additional magnetic field? If so, what is the direction of the additional magnetic field? Does it reinforce or counteract the original magnetic field?
