Question

In electromagnetic wave, according to Maxwell, changing electric field gives.

• A. Stationary magnetic field
• B. Conduction current
• C. Eddy current
• D. Displacement current

Answer 1

The correct option is D Displacement current

By Maxwell

$I_d=\frac{\epsilon dE}{dt}$

dE is electric field

$I_d$ is displacement current per unit area.

Hence changing electric field gives displacement current.
