So, even a magnetic field is generated by a charged particles accelerated. That's ok. It means that the only source of electromagnetic waves is a electric charge. But I've never seen a book or even a example in which a wave is produced by a permanent magnet. Even a pulsar produces its waves...

I think no. Because the only measurable variables on a colision is the distance, time and mass. The another things are calculated with that.

For transmitting energy, high amperages are a very bad idea due to joule effect. The advantage is generating a large amount of magnetic filed around it.

Every book I ever read describes a electromagnetic wave as a phenomena generated by charged particles accelerating. This will produce a change in electric field that induces a magnetic field. But, due to Maxwell equations a change in magnetic field will also produce an electric field. So, if a...
