Answer 1

$\huge{\orange{\underline{\red{\mathbf{ ♡ ANSWER♡}}}}}$

Michael Faraday was invented AC generator in 1822. Its simplicity masks its true importance as the first surviving electric motor.

How it works :-

When the armature rotates between the poles of the magnet upon an axis perpendicular to the magnetic field, the flux linkage of the armature changes continuously. Due to this, an emf is induced in the armature. This produces an electric current that flows through the galvanometer and the slip rings and brushes. The galvanometer swings between positive and negative values. This indicates that there is an alternating current flowing through the galvanometer. The direction of the induced current can be identified using Fleming’s Right Hand Rule.
