Picking up the thread from Andy higher up the page, yes, points are still in the syllabus for a BTEC in Vehicle Technology. Its probably an easy way of explaining coil switching. The course then rapidly progresses to inductive pick ups, hall effect switches etc., and by the third session the students are using 'scopes and DMM's, but you cannot ignore the basics.
