# What shape does the Induced Electric Field Lines take when in a region there is Non Cylindrical Time Varying Magnetic Field?

Everywhere in the literature I have across, I find that whenever the discussion of the Induced electric field comes, it is discussed around a cylindrical time-varying magnetic field. The induced electric field turns out to be circular in this case.

My question is, what shape does the induced electric field take when the magnetic field is time-varying but non-cylindrical?

In fig. 2 shows the distribution of the magnetic field in various sections $$y=0,0.2, 0.4, 0.6, 0.8, 1$$
In fig. 3 shows the distribution of the electric field in various sections $$z=0,0.2, 0.4, 0.6, 0.8, 1$$.It is seen that when moving away from the center of the coil, the lines of the electric field become circular as @garyp noted.
