8.2 Displacement Current Simulation

This simulation illustrates the displacement current Simulation that arises in a charging capacitor.

• As the electric field between the plates changes, it creates a magnetic field around it.
• The faster the electric field changes, the stronger the induced magnetic field.
• This is described by the Ampere-Maxwell Law: \[ \oint \vec{B} \cdot d\vec{l} = \mu_0 \epsilon_0 \frac{d\Phi_E}{dt} \]

Use the slider to increase the rate of change of electric field and observe stronger magnetic field circles.
