Why don't light waves move magnets?
We know that light travels through the vacuum of space because it is a self perpetuating system of electronic and magnetic waves.
Since this is the case, why do we not see the magnetic wave of light move magnets, or even make a magnet vibrate?
Is it simply because the magnitude of the magnetic wave does not exert enough force to move magnets?
If so can we not create an E&M wave with a large enough magnitude to move magnets?
OR can we create a magnet small enough to be moved by a magnetic wave?
Any insight into this topic would be helpful

In the IR range, you can have molecules that will change their vibrational state to incoming radiation.
Generally speaking, you should probably consider the oscillating electric field first, which interacts with any atomic dipoles (i.e. all matter, not just magnets).
