I meant that they only obey those Laws by a short period of time.
I meant they are not continuous. They don't produce sine waves.

The subject is so complex that nobody really knows everything.
There is no good picture of the electromagnetic mechanism.
All the pictures have strong arguments against them and that's
what keeps us here trying to figure out the best picture.
Most of the people gets satisfied with equations and give up
to figure a picture. They are not engineers and they never
disassemble machines just for the fun and try to understand them.
They claim there is no forces but they always use the safety belt
when they drive a car.
Magnetism is a force that acts at distance.
In the case of sinusoidal AC machines (synchronous or induction)
it is a matter of poles repelling similar poles (N-N or S-S), not
poles attracting poles (N-S or S-N). Energy is stored during
half cycle time and given the other half. There is a delay on the
process. There is real power (equal to mechanical energy) plus
apparent power that is current flowing out of phase with no work
done, etc., etc.

What magnetism is a puzzle. Lines of force?
For sure it is a force even without knowing how a force can be
transmitted at distance. For sure is not radiation because a 300
MW (megawatt) generator translated into radiation will be a power station
that will emanate so much radiation that it will be seen light-years away.
