Induced Electric Field MCQ - Practice Questions with Answers

Whenever a magnetic field is varying with time, an induced electric field $E_{\text {in }}$ is produced in any closed path, whether in the matter or in empty space. This Induced electric field is directly proportional to induced emf as $\varepsilon=\oint \overrightarrow{E_{i n}} \cdot \overrightarrow{d l}$. And this $E_{\text {in }}$ is given as

$$
\varepsilon=\oint \overrightarrow{E_{i n}} \cdot \overrightarrow{d l}=\frac{-d \phi}{d t}
$$

This is known as an integral form of Faraday's laws of EMI.
Properties of Induced electric field-
- The induced electric field is different from the electrostatic field. As it is non-conservative and non-electrostatic in nature.
- Its field lines are concentric circular closed curves.
- This field is not created by source charges.
- Its direction is along the tangent to its field lines.
