The London Study Group had a talk from an EMC expert recently on this topic; note that two of the 2010 module 7 questions were closely related to this subject.
I am hoping that he may permit me to share his Powerpoint presentation on this forum. In the meantime I am attaching a document that I was inspired to produce; I found that I didn't need all the time I had set aside last weekend for reviewing answers for the forthcoming mod2/3 Signet event, which gave me the opportunity to do this.
It is not directly aimed at answering any specific exam question, but hopefully will provide a resource useful for tackling some of these; I have gathered together information from a range of documents and my own experience to attempt to shed some light onto an area of mystery for many. For the IRSE exam you only need an appreciation of the overview, so I have spared you 3 dimensional Maxwell equations- divs, grads, curls and all the rest of university maths that in truth I have all but forgotten
