How Eddy Currents Produce Attractive Electromagnetic Forces--Maglev Hello, I am working on a paper about maglev systems and am trying to describe attractive electromagnetic suspension systems, but I am having a little trouble exactly visualizing how this works, which from what I have read is due to magnetic fields through eddy currents. In repulsive electrodynamic suspensions systems, this all makes a lot of sense to me. The changing magnetic field runs through the surface of the tracks and sets up eddy currents that oppose the time-changing flux, which in turn create a magnetic field of their own. The result of the two magnetic fields is magnetic repulsion, due to the magnetic pressure between the two systems. But how can eddy currents be used to explain the attraction. When I draw the diagrams of magnetic fields going through a conductor, I am only able to figure out a way to draw them such that the induced magnetic field is repulsive. Can anyone help me see how they can be attractive as well? Thank you!
