    how are magnetism and EM waves connected or do we not know (as a race)
    and is there any interesting theorys to how?

    At least for types of radio waves...they are only pulses of magnetic waves being shot into the air as far as I know. All you have to do is tap together two terminals of a battery connected to a long thing wire, and you can make a type of archaic radio transmission. Were still learning though exactly how its all connected, but we have a sufficient enough understanding to do certain things utilizing it in technology.

    I think that theres a difference between electromagnetism and normal magnetism. Magnets are based on a circulating field of energy, that creates a bound together series of depletion and excessive energy zones; while EM fields only create a singular type of zone or another, that does not necessarily require its opposite to be bound to another segment of its body. It could either be that, or just the way that the zones are accomplished....You could say that the magnets field is infinite without interruption, and that an EM fields is not, since its effect has to return to its transmission source at one point or another...otherwise we could not have a working circuit.

    one more question....
    where do magnets get there energy from? (not including electromagnets)
    or if its consider a force it doesnt matter but can someone indicate which one it is

    Magnets are materials that are able to absorb and hold an electromagnets field. The original field imposed upon a magnet will determine the magnets outcome field.

    Natural magnets I believe, get their field from the earths magnetic field. Over billions of years the material absorbs enough of it to take on its characteristics.

    Magnets that we make though, are exposed to an IMMENSE electromagnetic field for a little while.

    Naturally, magnet material doesn't do anything; it is like a sponge able to absorb what it is exposed to.
