The first electric generators used direct current, so they needed to be reversed manually on a regular basis in order to work properly. nikola tesla saw this as an inefficient way to produce electricity. as a result, tesla used the idea of the rotating magnetic field, which had been developed by françois arago, to invent the induction motor, which reverses automatically. how is this an example of a scientist applying creativity to solve a problem?
a-tesla investigated a new problem that no one had considered before.
b-tesla used another scientist’s research as inspiration.
c-tesla designed a new experimental method for research.
d-tesla invented an entirely new concept to replace an inefficient design.
