Abstract
The behavior of a circuit formed by two inductors magnetically decoupled
from each other, with identical inductances or not, associated in
parallel with a resistor, is studied in this article. It is shown that
when the inductances of the inductors are identical, half of the initial
energy is dissipated in the resistor, regardless of its value. For
unequal inductances, the energy lost depends on the ratio between the
values of the inductances, which can be greater or less than half of the
initial energy. It is also shown that, regardless of the circuit
parameters, whatever they may be, the algebraic sum of the magnetic
fluxes of the two inductors is constant and equal to its initial value,
not varying over time along the energy transfer process between the
inductors.
