How to calculate retarded potential (for magnetic field calculation) for a group of current carrying loops where the magnitude of current is changing?
For constant current, the magnetic field seems to be easy to calculate because of Biot-Savart Law. For a loop having varying magnitude of current (simplifying an electromagnet), however, it seems that ...

EMF developed in a varying magnetic field
Let's say there's a cylindrical varying magnetic field (varying at a constant rate) and I have a conducting body, let's say a rod placed in a plane perpendicular to magnetic field. I am having a ...
