GEOLOGY

Detailed explanation-1: -In the similar way, a changing magnetic field produces an electric current in a wire or conductor. The relationship between electricity and magnetism is called electromagnetism.

Detailed explanation-2: -Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow. Electromagnetism is the interaction of these two important forces.

Detailed explanation-3: -Oersted made the discovery for which he is famous in 1820. At the time, although most scientists thought electricity and magnetism were not related, there were some reasons to think there might be a connection. For instance, it had long been known that a compass, when struck by lightning, could reverse polarity.

Detailed explanation-4: -Electromagnetism is a branch of Physics, that deals with the electromagnetic force that occurs between electrically charged particles. The electromagnetic force is one of the four fundamental forces and exhibits electromagnetic fields such as magnetic fields, electric fields, and light.

Detailed explanation-5: -Electromagnetism involves two main relationships: electric currents produce magnetic fields, and. moving or changing the strength of magnetic fields can produce an electric current.
