We consider an electric field created by a charge distributed in the volume of a cylinder of radius R: 

We can affirm that: 

We consider an infinite wire, of (Oz) axis carrying a variable current I(t).

The magnetic field created at any observation point M at a distance r from the wire is: 

We can affirm that

The displacement current density is:
