Most electromagnetic waves are produced by man. Examples of electromagnetic waves are radio waves, micro waves, infrared waves, x-rays, ultraviolet rays etc.
The sun also produces electromagnetic waves in the form of ultraviolet rays.
An electromagnetic wave is created by moving charges back and forth, which produces electric and magnetic fields, which travel at great speed.
