Furthermore, by 1820, the Dutch researcher Hans Christian Oersted found the connection among power and magnets which a year later French physicist Andre Ampere extended it further.

Electromagnetism is utilized in all sort of electronic gadgets we use today, for example Hard circle drives, speakers, engines and generators. They are additionally utilized for MRI machines to take photos of your body parts to recognize any medical problem!
