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.

You talking about diffraction?

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).
