The pan gets evenly hot wherever it comes in contact with the bit of the
unit which generates heat - which is a round area in the centre.
Different units will have slightly different diameters. If the pan is
wide, the centre will heat up first, very quickly, and rest of the
surface will heat by conduction. I have a nice Windsor pan (smaller
bottom, slopes out to the top) which fits the hot-spot perfectly, and a
semi-wok type which works well, as well as the little frying pan which
came with the hob. Oh, and my Fagor pressure cooker works on it, too.
