devised between the first able apparatuses to produce to electric
current by means of electromagnetic induction. The
Pacinotti it described in a communication the “New
one I try” in 1864, and called then “ring
it consisted essentially in a ring around which a copper thread was
wrapped to spiral: the ring was free to rotate horizontally between the
poles of a magnet or elettrocalamita.
For the phenomenon of electromagnetic induction,
uncovered from M. Faraday
in 1831, the rotatorio motion produced to an
electric current in the
thread, and, viceversa, the electric current passage in the thread made
to rotate the ring, which, in such a way, acted as or from dynamo or
from electric motor.
in a backing and engaged in the academic career, it did not know to
take advantage of its invention commercially: the dynamo thus was
constructed on industrial scale from Belgian Z.T., which Pacinotti had
shown and described its apparatus during a visit in France.
