the generation of a current by a changing magnetic feild
becoz alternater has work on principle of electomagnetic induction .
Electromagnetic induction is the process of generating an electromotive force (emf) by changing the magnetic field around a conductor. This phenomenon was discovered by Faraday in the 19th century. It is the underlying principle behind the operation of electric generators and transformers.
when and where was the electomagnetic field
I think electomagnetic waves...
Sure it can
Ultraviolet radiation
an electromagnetic field is the region where the elctro megnetic forces exist
electromagnetic waves are energy transfered through out medium which is energy
the practice of modern weather forcasting and the electomagnetic resonance
The bulb contains electomagnetic waves that makes the bulb light.
Because they have the shortest wavelengths
Yes. Light IS electromagnetic waves.
