Question

According to Maxwell, a changing electric field produces

• A. Emf
• B. Electric Current
• C. Magnetic Field
• D. Radiation pressure

Answer 1

The correct option is C

Magnetic Field

Correct option is C: Magnetic Field

Explanation for the correct option:

1. As per the ampere's Law which was further modified by Maxwell

$\begin{array}{l}\oint \overrightarrow{B}.\overrightarrow{ds}={\mu }_{0}I+{\epsilon }_0{\mu }_0\frac{d{\varphi }_E}{dt}\end{array}$

where, $\overrightarrow{B}$is Induced magnetic flux

$I$ is electric current

2. An electric current $I$ or a changing electric flux through a surface produces a circulating magnetic field around any path that bounds that surface."

Hence, option C is correct.
