The birth of the electric machines: a commentary on Faraday (1832
... Michael Faraday was born in 1791 in Newington Butts, now in South London, but then no more than a village in rural Surrey. He was the son of a blacksmith who had moved down from Cumbria in northwest England just before Michael was born. His family were not well off and Faraday received a typical wo ...

... (a) Two electrodes can be connected to a voltage supply. If the voltage is sufficiently large & the electrodes are in a vacuum, the negative electrode (cathode) can get hot enough to emit, or ‘boil off’, electrons. The electric field between the electrodes will accelerate the electrons towards the posi ...

... The electric and magnetic fields are no longer interconnected in the static case. This allows us to study electricity and magnetism as two distinct and separate phenomena, as long as the spatial distributions of charge and current flow remain constant in time. We refer to the study of electric and ...
