Context: <response>: In 1827, Hungarian physicist Ányos Jedlik start to dey do experiment with electromagnetic coils. After Jedlik solve the technical wahala of continuous rotation with the invention of the commutator, he call him early devices "electromagnetic self-rotors". Even though dem dey use am only for instructional purposes, for 1828 Jedlik show the first device wey get the three main components of practical DC motors: the stator, rotor and commutator. The device no use permanent magnets, as the magnetic fields of both the stationary and revolving components na only produced by the currents wey dey flow through their windings.
