The discussion clarifies the nature of electric and magnetic dipoles and their associated fields. It establishes that electric fields are generated by changing magnetic dipoles, while moving electric monopoles generate magnetic fields, as described by Lienard-Wiechert potentials. A stationary magnetic dipole does not produce an electric field unless it is changing. The distinction between electric and magnetic dipoles is based on their structure: electric dipoles consist of positive and negative charges separated by distance, while magnetic dipoles are formed by current loops.

No. You have to have a changing dipole.Isaac0427 said:Is there an electric field in a non-moving magnetic dipole
Yes. This is described by the Lienard Wiechert potentials.Isaac0427 said:is there a magnetic field in a moving electric monopole?
Thank you.DaleSpam said:No. You have to have a changing dipole.
Yes. This is described by the Lienard Wiechert potentials.
Then how can a 2-sided magnet be a magnetic dipole?DaleSpam said:No. Magnetic dipoles are formed by small loops of current. Electric dipoles are formed by positive and negative charges separated by a small distance.
Ok. I see what I got wrong. What is really misleading me are the pictures of current loops. They all draw the same field lines, however some sources say that the field lines show the magnetic potential, and some say the field lines are showing the magnetic field.Isaac0427 said:Then how can a 2-sided magnet be a magnetic dipole?
