Is the Wikipedia's explanation of the working principle of an induction motor actually a nonsense? I read the article about the working principle of an induction motor on Wikipedia [ https://en.wikipedia.org/wiki/Induction_motor#Principle_of_operat -
The electric field intensity E is given by E=E*sin (wt-Bz) in free space. What is the value of the magnetic field strength H, magnetic flux density B, and electric flux density D? -
