A magnetron may be used to generate radio-frequency currents and fields
at high power and high frequencies.
The source of RF in most microwave ovens is a magnetron.
A magnetron tube inside of the microwave produces the waves and a fan circulates them.

Yes.
Radio waves are harmful to people because they give off radiation. Radiation is known to cause cancer in humans.
As far as we know.
pulsar
mobile phones give off radio waves to special stations which are built especially to connect calls, as they used to have an operator this is what now is used instead of the operator at this modernised age.
I had to think for this one but me being eleven I'm surprised nobody could answer but there are none on earth that i know of its in space a star, a star gives off radio waves.
Computers give off mostly heat, but also give off magnetism in the form of radio waves. Plus their displays give off light energy and the speakers give off sound waves. The fans inside create kinetic energy.
A radio altimeter bounces radio waves off the ground to detect elevation.
Pulsar, since you would need some mechanical device to produce radio waves.
Yes, black holes can emit radio waves. These radio waves can come from material accelerating near the black hole before being consumed, or from the interaction of the black hole with its surrounding environment. Studying these radio emissions can provide valuable information about the properties and behavior of black holes.
