I was asking my course mentors and they said it doesn't but looking at
the diagrams it seems to do that. Even the lines in the diagram show direction change, which in all magnetic field diagrams the line of
force are directional.
It is the alternating electric field that maintains the alternating magnetic field and vice-versa, so both fields alternate, they are at right angles to each other, and both are at right angles to the direction of propagation.
I was thinking the polarity .. could be the cause of defraction for obsticals smaller than the wave length. The polarity and charge
oscilation defracts on like charge or magnetic field as the wave
(photon) passes near field forces.
You talking about diffraction?
Then I thought more probably does happen but it doesn't explain why the longer wave lengths wouldn't defract consistently near a like charge,
or even attracted to a opposite charge.
The electric component of an EM wave is a field, not a charge. It will cause movement of charge (which is how many antennas pick up the energy on
eceivers).
