WebAn emf is induced in the coil when a bar magnet is pushed in and out of it. Emfs of opposite signs are produced by motion in opposite directions, and the emfs are also reversed by reversing poles. The same results are produced if the coil is moved rather than the magnet—it is the relative motion that is important. Web2 The purpose of this section is to explain the types of EMF that can be generated within subsea cables associated with offshore wind farms and to summarise the potential environmental impacts of EMFs. This section is not an impact assessment, the impacts of EMFs are considered in more detail in
