Question:
If we put some kind of bodies nearby a magnet we can feel
a repulsive or attractive force acting on them. Now, as long as light
may be considered an electromagnetic wave travelling the space, I wonder
why we can't detect such a force if we put those bodies nearby a source
of light (its magnetic component).
Does it depend on the relative low intensity of the currently available
sources of light?
Or is it due to rapidly changing vectors of forces associated with the field?
Or is the question completely wrong?
(I'M AWARE THAT MY IDEAS IN THIS FIELD ARE VERY NAIVE.)

Replies:
The rapidly changing field direction is the major reason for no noticeable
force. Some force exists, as can be seen in a UHF television antenna. The
electrons in the antenna can oscillate at the frequency of the magnetic
wave. It is not enough to move the antenna, just some of the free electrons
within.
