Happy Birthday Henry with the Magnetic Personality

What is the opposite of “resistance” ?

Inductance … which we measure in “henrys”.

And if Joseph Henry had been quicker on the draw and published first – then maybe we would be measuring capacitance in “josephs” rather than “farads” after Michael Faraday … the guy who published his findings first.

Henry was the first Secretary of the Smithsonian Institute –

A real American Scientist born on this day in 1797 and lived 80 years.

He lived most of his life and passed in Washington DC in 1878 … 80 years !

This was obviously when actual intelligent people lived in Washington DC

What was Joseph Henry’s main contribution to science ? Himself (in my opinion)

And of course his discovery of self-inductance

… a wacky-weird thing that happens with electromagnetism.

Fun to do at parties with a bunch of Dr Who fans around …

Without harnessing the electromagnetic principle of self-inductance there would be NONE of our electric contraptions we rely on today … NONE … maybe some battery operated gadgets … Thomas Edison would actually appear to be smart if that were true …

Thanks to Joseph Henry – you can listen to your stereo, use a suck-broom on your floor, use a radio and basically use anything that plugs into a wall socket …

He didn’t “invent” the wall socket – he discovered how to get the power to the socket basically …

Look up what a TRANSFORMER is … and what INDUCTANCE is …

Class dismissed …
