Answer:
generator
Explanation:
A generator works on the principle of Faraday's law of induction. When a conducting wire is run into a magnetic field i.e. when there is changing magnetic flux around the wire, an emf is induced in the wire which produces current.
Induced emf:
[tex]e=-\frac{d\phi}{dt}=-\frac{dBA}{dt}[/tex]
A generator produces by moving wire made of conducting material through a magnetic field.
