Induced Electric Field - Practice Questions & MCQ

 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

$
\text { as } \varepsilon=\oint \overrightarrow{E_{i n}} \cdot \overrightarrow{d l} .
$

And this $E_{i n}$ 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.
