Waving a magnet will not generate an EM wave, it won't even induce a
current unless there is a conductor to hand.
From Maxwell, del cross E = -dB/dt
Maxwell's equations come as a 'set' to generate an EM wave,
I regret that you have only part of the story, for Maxwell's Equations
describe _ALL_ electrical phenomena.
Nope; disproved mid-20th century.
Maxwell's equations are a classical approximation to quantum electrodynamics
much like Newtons Laws are a classical approximation to situations much
slower than the speed of light.
Maxwell's equations do not apply when the particle nature of electromagnetic
radiation is concidered or for very strong electric fields, for example.
