How do two waves cancel without interacting?

No interaction is required in order for fields to cancel. Only that
they occupy the same space at the same time and be of the correct
amplitude and phase.

And are put into a load.

As waves are completely independant, then they never interact. A load
is required to reveal the cancellation. No load, and any issue of
cancelling fields is strictly limited to what goes on between the
ears.
