But what radiate? Magnetic whirls or pressure-like electric wave?
S*
magnets don't whirl and 'electric waves' are not like pressure... they
magnetic and electric field vectors are at right angles to each other and
the direction of propagation... both the electric and magnetic components
are needed for propagation... you can't have one without the other.
It's hard to tell, but he's probably referring to the curl of a
magnetic field which he obviously doesn't understand. The idea of
a "pressure-like electric wave" is pure fantasy.
There is the fantastic example:
