Expert Answer
Displacement current is due to change in electric field in dielectric medium. This is occuring while charging the capacitor.
The displacement current can be considered to be distributed throughout the volume between the plates of capacitor.
The associated magnetic field can be calculated in a similar manner to that due to a thick wire carrying (conduction) current.
Direction of the magnetic field created by the displacement current can be found by applying the right-hand rule
in the usual way - thumb points in the direction of the (displacement) current, fingers wrap around in the direction of the magnetic field.
The direction of the displacement current itself is in the same direction as E if E is increasing with time (dE/dt > 0).
When E is decreasing with time the displacement current is opposite to E (dE/dt < 0).
The presence of the displacement current would be signaled by detection of its associated magnetic field.
Assuming only a displacement current we can write Ampere's Law,
Thus, unless dE/dt and A/l are very large, magnetic field B due to displacement current will be very small.
