No, consider a coil of wire conducting a constant current. There will be a static magnetic field around it, but no electromagnetic waves with E X H = P
Moving charges.Another opinion:If an electromagnetic wave were made up of moving charges, you'd see lightningshoot out of the meatloaf every time you nuke it in the microwave.While moving charges may generate electromagnetic waves, the charges stay wherethey are, while the waves go sailing away. The waves are made up of electrostaticand magnetic fields.

No. Electromagnetic waves are produced by accelerating charges (NOT by moving charges, they have to accelerate); a neutron has no net electrical charge.
He generated electromagnetic waves by accelerating charges back and forth rapidly in an antenna. He detected the waves by using a similar antenna that would convert the electromagnetic waves into electrical signals.
According to Maxwell's Equations electromagnetic waves are able to propagate without the need for any medium: moving electric charges induce a moving magnetic field, a moving magnetic field induces moving electric charges, ad infinitum...
Electromagnetic waves are created by the acceleration of electric charges.
Electromagnetic waves.
When electric charges vibrate, they produce electromagnetic waves. This is due to the oscillating electric and magnetic fields generated by the moving charges. These waves can take various forms such as radio waves, light, or X-rays depending on the frequency of the vibrations.
Electromagnetic waves.
Any electric charge undergoing acceleration will produce Electromagnetic waves. This is by far the most common way.If an oscillating electric field is synchronized with an oscillating magnetic field of exactly the same frequency a beam of light will be produce where the two fields are orthogonal in all dimensions.
No. Radio waves are a type of electromagnetic waves.
No direct relation; electromagnetic waves are transmitted by photons. However, electromagnetic waves are often caused by the acceleration of electric charges, and those charges are usually electrons. Also, electromagnetic waves are emitted and absorbed when an electron (in an atom) changes to another energy level.
