"Yes, the common thinking is that current changes direction to oppose
the forward moving current as with a reflection where the eddy current
moving in the reverse direction cancels the eddy current moving in the
other direction."

Transformers are laminated to reduce eddy current core losses.

Reverse currents on a transmission line or on an antenna are usually
called the reflected current.

Reflections are caused by discontinuities in the path of the EM wave.

In the case of an open circuit, the reflection coefficient is infinite
and the incident and reflected waves have the same magnitude and phase.
The voltage at the discontinuity is thus doubled. See Terman`s 1955 opus
page 89. But, the current goes to zero as conduction ends at the open
circuit. No energy is lost in the open circuit. It is just concentrated
in the electric field as the magnetic field loses its energy.
