Confusion with the direction of E-fields near conductors

In summary: I don't understand what you are trying to say.Are you implying that the tangential field just inside is also a tangential field just outside. And since the just inside tangential field is zero so is just outside tangential...No, I'm asking you to deduce the value of the tangential component from what I (and @ergospherical) have said.No, I'm asking you to deduce the value of the tangential component from what I (and @ergospherical) have said.

What does that mean? I didn’t catch you. Also Please complete your sentence.
Change in e sub r.
This changes the ratio between B field and E field intensity in the location.
tangential current exists to carry this E field component.

<h2>1. What causes confusion with the direction of E-fields near conductors?</h2><p>The confusion with the direction of E-fields near conductors is caused by the interaction between the electric field and the conductive material. This interaction can lead to changes in the direction and strength of the electric field, making it difficult to determine the exact direction near the conductor.</p><h2>2.
