“What happens when a conductor moves through a magnetic field?”
Let’s consider a situation. Say we have a conducting material, such as copper or iron. And let’s also say that we are going to pass this material through a magnetic field. Since conductors contain electrons, and when electrons move at a speed relative to a magnetic field, a force will be generated. And since conductors allow electrons to move within the internal structure of the material, these electrons will swirl around in a way so that they generate a magnetic field that opposes the original magnetic field. Because such movement of electrons are circular in nature, scientists and engineers have termed this phenomena eddy currents.
