Title: Alternators, dc generators and alike
Post by: marcosbk on June 19, 2020, 10:02:02 AM
is known the procedure to create electrical power by moving a coil through magnetic field or a magnetic field through coil, as dc generators or alternators.
all known or better said used procedures requires a mechanical work from which we calculate system efficiency.
what if we provide a moving magnetic field without using mechanical work?
will there be something that will not suffice?
to me, the theory looks fine,according to present electricity laws.
pleased to hear .
rgds to all
