Question

(Figure 1) shows an increasing magnetic field and the electric field that accompanies it according to Faraday's law. The magnetic field is increasing at an increasing rate.

E into the figure E out of the figure

Does the behavior of the electric field produce an additional magnetic field?

Answer 1

according to Faraday's law cahnge in the magnetic filed induces emf which is proportional

to the magnitude of the electric field and the emf induced varies with the rate of the change in magnetic field

e =- A dB/dt

since the magnetic field is increasing at an increasing rate, the magnitude of the electric field will also increase

(b)

changing electric filed produces magnetic field. the current produced towards the increasing electric field produce a magnetic field which points toward the left in the region of original magnetic field . the prouced magnetic field counteracts the original magnetic filed.
