induction coil invented 1836 by nicholas callan , same time as charles page (who made a 10 ton electric bus in 1850)
theres a progresion of inventors of the induction coil , heinrich ruhmkorff in 1851 , leading up to teslas work with HV induction coils and 1/4 wave lengths .
heres a good modern circuit

1836 to 2016 is 170 years we use this coil every day . It uses a DC make and break to turn DC into HV with out using motion , its the Flux that is in motion.
make and break interupters have gone from rotary rheotomes , shown in Tesla canadian patent , magnetic reed switch , cam driven points and now solid state ignition systems
heres a rheotome

I think the most amazing thing to me about inductors are how they work with an air core.
