Circularity is a powerful concept, the idea of a closed loop even more so. In circular motion there is magic, just as there is in electro-magnetism. … - Eric Laithwaite
" "Circularity is a powerful concept, the idea of a closed loop even more so. In circular motion there is magic, just as there is in electro-magnetism. But it only manifests itself when it is, like (shall we say for the moment, rather than a 'reflection' of) its 'neighboring head', truly three-dimensional. ...We can induce current into the one [coil] from the other by means totally unintelligible to us, but to which we give the name 'electromagnetic induction'. But if I place one coil with its axis at right-angles to that of the other, there is no induced voltage. It is as if the two circuits lived in different worlds... What is the meaning of perspective in a four-dimensional space?

About Eric Laithwaite
Eric Roberts Laithwaite (14 June 1921 – 27 November 1997) was a British electrical engineer, known as the "Father of " for his development of the and maglev rail system. He and Fredrick Eastham designed a self-stable magnetic levitation system called (which incidentally appeared in the film The Spy Who Loved Me). Laithwaite derived an equation for "goodness", which parametrically described motor efficiency in general terms, and which he interpreted as implying that motor efficiency increases with size. He made many television appearances, including the to young people in 1966 and 1974. Laithwaite was also a keen amateur entomologist and the co-authored The Dictionary of Butterflies and Moths (1975).

[In] the first efforts of Fred Barwell and myself to try out the feasibility of linear motor drives for railways... we built an 80-foot track in the laboratories of Manchester University... Having put a seat on this vehicle and given rides to daily newspaper reporters (acceleration 0.5 g), we had all the publicity we needed...
West Germany branched... into... another new topology with a large-scale demonstration of the '' system... Permanent s were used to provide the lift from the underside of a ground rail. Guide wheels were used to control the gap. The philosophy... better to provide a lifting force of 120 per cent of the vehicle weight and run the wheels on a 'ceiling'...
The Jabberwock was a monster with many heads. As such it resembles... the manner in which we divide our science into Physics, Chemistry, Biology, etc., and then Physics into Heat, Light, Sound, Magnetism and Electricity. Often one can spot the various heads as being Laws of Physics, and some of them look into mirrors, see their reflections and think that the total number of their kind is bigger than it really is. Thus they attempt to co-exist with their own shadows and reflections. One of the best examples... is... Laws of Electromagnetic Induction.
