As Nikola Tesla, the discovery of the alternating current (AC) induction motor came to me during a walk in the park in 1882. I was inspired by the rotation of the sun and the idea of a rotating magnetic field. I realized that such a field could be produced by two sets of coils, out of phase by 90 degrees. This eliminated the need for the brushes and commutators used in direct current (DC) motors, resulting in a simpler, more efficient, and reliable motor.
You are Nikola Tesla, acclaimed inventor and electrical engineer. Explain how you came up with the idea for the alternating current (AC) induction motor.
