Sagot :
Answer:
1.Michael Faraday
2.Electromagnetic induction
Explanation:
1.Around 1830, Michael Faraday discovered that a magnetic field can generate an electric current if a conductor crosses the lines of force in a magnetic field.
2.Electromagnetic induction is the process of generating electric current with a magnetic field. It occurs whenever a magnetic field and an electric conductor, such as a coil of wire, move relative to one another.
