electromagnetism - Eddy current induce EMF


Q1 Suppose there is a wire having AC current so as ac current is alternating it creates back EMF whether that back emf produces current?


If yes then that current is same as eddy current or not?


And that current will be alternating too so can it will creates another back emf and till this process continues or not?


Q2 genratore produces Ac current so that AC current be able to produce a motor action or not


Q3 motor have is continously moving in a magnetic flux be able to produce back EMF? If yes then that back emf will again produce current and according to law current carrying conductor have force acting on it in a magnetic field the force will again act on it. Whether that force be opposite to previous force or not

Understanding Stagnation point in pitot fluid

What is stagnation point in fluid mechanics. At the open end of the pitot tube the velocity of the fluid becomes zero.But that should result...
